Existing implementation was using the same RRC prototype filter on transmit and receive filterbanks. But, the receive input from the device is 6.25 Msps vs 3.84 Msps, which leads to wider RRC filter bandwidth than specified and excess noise being present in the signal. Correct by scaling the time domain pulse by a factor of 384/625 to obtain the appropriate pulse shape. Signed-off-by: Tom Tsou <tom@tsou.cc>
