I'm studying about FMCOMMS2-EBZ and ZEDBOARD. I used No-OS to transmit sin_lut table and use BPSK to modulate data, but I don't know how to configure filter coefficients in order to receive data exactly. I followed the instruction on wiki.analog.com to design a low pass filter using Matlab tool but when I copy the coefficients into tx_fir_config and rx_fir_config tables in main.c, it does not work because when I when I use console and type tx_fir_en? command it returns 0 and when I use Matlab to plot received data, it's not BPSK constellation. So I want to know how to enable FIR filter on transmit path and receive path and the meaning of filter's coefficients in Matlab.
Thank you for reading,
