Using MATLAB programming, resulting in a 16QAM baseband signal, and the real multiples of the interpolation calculation. The requirements of symbol rate 1 MSymbol/s, the root mean square raised cosine filter shape, roll-off factor = 0.5. Generate {1,0,1,1, ...} of the pseudo-random sequence, mapping, four times the shaping filter, FIR half-band filter, in fact, several times interpolation filter, the final output of 4.315 times the time domain/frequency domain response. Given the signal sequence through all levels of filtering the time domain, frequency domain results
