We are using 16 Bit I/Q data with zero bbgain in the rx_intf module. We went through the receive signal path and found the areas that were having problems with low and high signal levels. This limited dynamic range to about 45dB. This was increased to 69dB dynamic range of successful decoding of HT MCS0 packets. In our system, the ADC I/Q data ranges from fully saturated 0x7fff/0x8000 to about 4bits of noise at the low end.
