Description: function receiver_40a
receiver_40a is a demo of a 40 channel receiver, demodulating 30 channels,
of nominal symbol rate 20 MHz, separated by 28 MHz centers (1.4 times symbol rate)
input sample rate is 40*28 = 1120 MHz.
receiver performs a 40 point transform on the output of a 40-stage polyphase filter
the polyphase filter operates at input rate but outputs at 2 samples/symbol or
40 MHz. The resampling rate is 1120/40 = 28-to-1, thus output 40-channels are
computed once for every 28 input samples. channelizer is not matched filter,
prototype filter is 10 wider than two sided bandwidth of input signal to accommodate
frequency uncertainty of separate channel centers.-function receiver_40a
