## Matlab program for QPSK mod required

respected sir, can u give me coding for qpsk in matlab????

## need help for changing BPSK to QPSK in BER Zero-Forcing eq.

here is i have a matlab code as follow : --------------------------------------------------------------------------------------------- clear N = 10^6; % number of bits or symbols Eb_N0_dB = ; % multiple Eb/N0 values K = 4; for ii = 1:length(Eb_N0_dB) % Transmitter ip = rand(1,N)>0.5; % generating 0,1 with equal proba

## Help me write program that creates QPSK signal in Matlab

Give A={a1, a2, a3, a4} Write matlab program creating sequence qpsk random signal {s(n)} n=1,...N-1 s(n) belong to A. -generate signal s(n)*p(t), p(t) is response of rise cosine. p(t) sampled faster than T of symbol: 10 . Write program illustrating sequence signal transmittin

## Doppler effect and phase shift correcting under Matlab

Hi everyone I think I've post in the wrong forum yesterday, so here is my problem. I have to make a matlab program in order to draw the IQ diagram for some signals as BPSK and qpsk. I have to correct the Doppler effect and the phase shift with PLLs. I think Costas loops are good for correcting the phase shift. But what about the (...)
