Re: qpsk demodulator using verilog code
Dear Sir,
I have built QPSK modulator like u said earlier. Now when it comes to demodulation i'm finding it very difficult. The modulated data must go thro low pass filter. I have absolutely no idea how to implement a LPF in verilog. will u plz help me...
The output of NRZ encoder is 1 bit signal. The sine wave generated using the program below is 8 bits.
My question is how to multiply a 1 bit signal with an 8 bit one and generate a QPSK modulated wave??
module Sine_Cos_Waves( clk, reset, sine, cos);
input clk, reset;
output [7:0]...
