For modulation orders beyond 4, the bit error rate performance of PSK in AWGN worsens. In the following figure, the QPSK and BPSK curves overlap one another.DPSK DPSK is a noncoherent form of phase shift keying that does not require a coherent reference signal at the receiver. With DPSK, ...

MATLAB provides the function fir1 to design FIR filters with the window method. As expected, the results are identical for either fir1 and ours. The reason for writing fir is to simplify the code and to show how the modulation property can be used in the design of filters different from lo...
and now it’s your ready signal to modulation. Matlab code : N = 10^4 ; % number of data up = 4; % upsampling data d = randsrc(1,N); du = upsample (d,up); x = conv(du,Root_Raised_Cosine); % your ready signal to go to modulate Reply Abdulaziz Azzam Zezoo August 8, ...
