1637 * 1) Tx power (depends on temperature), described elsewhere
1638 * 2) Receiver gain balance (optimize MIMO, and detect disconnected antennas)
1639 * 3) Receiver sensitivity (to optimize signal detection)
1641 *****************************************************************************/
1644 * SENSITIVITY_CMD = 0xa8 (command, has simple generic response)
1646 * This command sets up the Rx signal detector for a sensitivity level that
1647 * is high enough to lock onto all signals within the associated network,
1648 * but low enough to ignore signals that are below a certain threshold, so as
1649 * not to have too many "false alarms". False alarms are signals that the
1650 * Rx DSP tries to lock onto, but then discards after determining that they
1653 * The optimum number of false alarms is between 5 and 50 per 200 TUs
1654 * (200 * 1024 uSecs, i.e. 204.8 milliseconds) of actual Rx time (i.e.
1655 * time listening, not transmitting). Driver must adjust sensitivity so that
1656 * the ratio of actual false alarms to actual Rx time falls within this range.
1658 * While associated, uCode delivers STATISTICS_NOTIFICATIONs after each
1659 * received beacon. These provide information to the driver to analyze the
1660 * sensitivity. Don't analyze statistics that come in from scanning, or any
1661 * other non-associated-network source. Pertinent statistics include:
1663 * From "general" statistics (struct statistics_rx_non_phy):
1665 * (beacon_energy_[abc] & 0x0FF00) >> 8 (unsigned, higher value is lower level)
1666 * Measure of energy of desired signal. Used for establishing a level
1667 * below which the device does not detect signals.
1669 * (beacon_silence_rssi_[abc] & 0x0FF00) >> 8 (unsigned, units in dB)
1670 * Measure of background noise in silent period after beacon.
1673 * uSecs of actual Rx time during beacon period (varies according to
1674 * how much time was spent transmitting).
1676 * From "cck" and "ofdm" statistics (struct statistics_rx_phy), separately:
1679 * Signal locks abandoned early (before phy-level header).
1682 * Signal locks abandoned late (during phy-level header).
1684 * NOTE: Both false_alarm_cnt and plcp_err increment monotonically from
1685 * beacon to beacon, i.e. each value is an accumulation of all errors
1686 * before and including the latest beacon. Values will wrap around to 0
1687 * after counting up to 2^32 - 1. Driver must differentiate vs.
1688 * previous beacon's values to determine # false alarms in the current
1691 * Total number of false alarms = false_alarms + plcp_errs
1693 * For OFDM, adjust the following table entries in struct iwl_sensitivity_cmd
1694 * (notice that the start points for OFDM are at or close to settings for
1695 * maximum sensitivity):
1698 * HD_AUTO_CORR32_X1_TH_ADD_MIN_INDEX 90 / 85 / 120
1699 * HD_AUTO_CORR32_X1_TH_ADD_MIN_MRC_INDEX 170 / 170 / 210
1700 * HD_AUTO_CORR32_X4_TH_ADD_MIN_INDEX 105 / 105 / 140
1701 * HD_AUTO_CORR32_X4_TH_ADD_MIN_MRC_INDEX 220 / 220 / 270
1703 * If actual rate of OFDM false alarms (+ plcp_errors) is too high
1704 * (greater than 50 for each 204.8 msecs listening), reduce sensitivity
1705 * by *adding* 1 to all 4 of the table entries above, up to the max for
1706 * each entry. Conversely, if false alarm rate is too low (less than 5
1707 * for each 204.8 msecs listening), *subtract* 1 from each entry to
1708 * increase sensitivity.
1710 * For CCK sensitivity, keep track of the following:
1712 * 1). 20-beacon history of maximum background noise, indicated by
1713 * (beacon_silence_rssi_[abc] & 0x0FF00), units in dB, across the
1714 * 3 receivers. For any given beacon, the "silence reference" is
1715 * the maximum of last 60 samples (20 beacons * 3 receivers).
1717 * 2). 10-beacon history of strongest signal level, as indicated
1718 * by (beacon_energy_[abc] & 0x0FF00) >> 8, across the 3 receivers,
1719 * i.e. the strength of the signal through the best receiver at the
1720 * moment. These measurements are "upside down", with lower values
1721 * for stronger signals, so max energy will be *minimum* value.
1723 * Then for any given beacon, the driver must determine the *weakest*
1724 * of the strongest signals; this is the minimum level that needs to be
1725 * successfully detected, when using the best receiver at the moment.
1726 * "Max cck energy" is the maximum (higher value means lower energy!)
1727 * of the last 10 minima. Once this is determined, driver must add
1728 * a little margin by adding "6" to it.
1730 * 3). Number of consecutive beacon periods with too few false alarms.
1731 * Reset this to 0 at the first beacon period that falls within the
1732 * "good" range (5 to 50 false alarms per 204.8 milliseconds rx).
1734 * Then, adjust the following CCK table entries in struct iwl_sensitivity_cmd
1735 * (notice that the start points for CCK are at maximum sensitivity):
1738 * HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX 125 / 125 / 200
1739 * HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX 200 / 200 / 400
1740 * HD_MIN_ENERGY_CCK_DET_INDEX 100 / 0 / 100
1742 * If actual rate of CCK false alarms (+ plcp_errors) is too high
1743 * (greater than 50 for each 204.8 msecs listening), method for reducing
1746 * 1) *Add* 3 to value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
1749 * 2) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is < 160,
1750 * sensitivity has been reduced a significant amount; bring it up to
1751 * a moderate 161. Otherwise, *add* 3, up to max 200.
1753 * 3) a) If current value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX is > 160,
1754 * sensitivity has been reduced only a moderate or small amount;
1755 * *subtract* 2 from value in HD_MIN_ENERGY_CCK_DET_INDEX,
1756 * down to min 0. Otherwise (if gain has been significantly reduced),
1757 * don't change the HD_MIN_ENERGY_CCK_DET_INDEX value.
1759 * b) Save a snapshot of the "silence reference".
1761 * If actual rate of CCK false alarms (+ plcp_errors) is too low
1762 * (less than 5 for each 204.8 msecs listening), method for increasing
1763 * sensitivity is used only if:
1765 * 1a) Previous beacon did not have too many false alarms
1766 * 1b) AND difference between previous "silence reference" and current
1767 * "silence reference" (prev - current) is 2 or more,
1768 * OR 2) 100 or more consecutive beacon periods have had rate of
1769 * less than 5 false alarms per 204.8 milliseconds rx time.
1771 * Method for increasing sensitivity:
1773 * 1) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_INDEX,
1776 * 2) *Subtract* 3 from value in HD_AUTO_CORR40_X4_TH_ADD_MIN_MRC_INDEX,
1779 * 3) *Add* 2 to value in HD_MIN_ENERGY_CCK_DET_INDEX, up to max 100.
1781 * If actual rate of CCK false alarms (+ plcp_errors) is within good range
1782 * (between 5 and 50 for each 204.8 msecs listening):
1784 * 1) Save a snapshot of the silence reference.
1786 * 2) If previous beacon had too many CCK false alarms (+ plcp_errors),
1787 * give some extra margin to energy threshold by *subtracting* 8
1788 * from value in HD_MIN_ENERGY_CCK_DET_INDEX.
1790 * For all cases (too few, too many, good range), make sure that the CCK
1791 * detection threshold (energy) is below the energy level for robust
1792 * detection over the past 10 beacon periods, the "Max cck energy".
1793 * Lower values mean higher energy; this means making sure that the value
1794 * in HD_MIN_ENERGY_CCK_DET_INDEX is at or *above* "Max cck energy".

1885 * (weakest) chain should be "0".

1888 * 2: (1) reduce gain, (0) increase gain
1889 * 1-0: amount of gain, units of 1.5 dB
