<agc_exp_thres>,<ag
c_exp_slope>,
<agc_compr_thres>,
<agc_compr_slope> Set command sets the handset RX AGC value tuning
Parameter:
<agc_static_gain>
precompressor static gain. This is the gain applied to the input samples when
static gain is enabled. Meaningful Range is 0x2000 to 0xFFFF.
Value(agc_static_gain) = 8192
∗
10^(X/20) : X range is 0 to 18 dB.
<agc_aig>
pre-compressor gain selection flag. Write 0xFFFF to enable adaptive gain (static
gain disabled). Write 0x0000 to enable static gain (adaptive gain disabled).
Meaningful value is just 0x0000 or 0xFFFF.
<agc_exp_thres>
expansion threshold. This is the energy threshold of the input under which
expansion is applied. This parameter must be less than agc_compr_thres.
Meaningful range is 0x0 to 0x2580. Write 0 to disable the expander.
Value(agc_exp_thres) = 128
∗
(X+75) : X range is -75 to 0 dBm0mu
<agc_exp_slope>
expansion slope. This is the slope of the expander gain when expansion is
applied. Meaningful range is 0xFF01 to 0xFFF6.
Value(agc_exp_slope) = 256 * X : X range is -0.04 to -0.996.
<agc_compr_thres>
compression threshold. This is the energy threshold of the input above which
compression is applied. Meaningful range is 0x0 to 0x2580. This parameter must
be greater than agc_exp_thres.
Value(agc_compr_thres) = 128
∗
(X+75) : X range is -75 to 0 dBm0mu
<agc_compr_slope>
compression slope. This is the slope of the compressor gain when compression is
applied. Meaningful range is 0x8000 to 0xFFFF.
Value(agc_compr_sloop) = 65536 * X : X range is 0.50001 to 0.99999
Note: these values are automatically saved in NVM.
