In recent years development in the field of communication lead to the development of modulation techniques. Selection of modulation techniques depends on signal to noise ratio (SNR), bit error rate (BER), Low multipath propagation etc. For this purpose QPSK (Quardrature phase shift key) and QAM...

MATLAB provides a powerful platform for implementing and simulating digitalmunication systems. The code snippet provided in the previous section demonstrates how QPSK modulation and demodulation can be implemented using MATLAB. The code generates a random QPSK modulated signal, displays the signal in a ...
QPSK调制与解调 (Matlab仿真) QPSK调制与解调 (Matlab仿真) 1. 一般在仿真的时候,大家都喜欢直接做等效基带仿真(类似于星座点的仿真)。 1. 一般在仿真的时候,大家都喜欢直接做等效基带仿真(类似于星座点的仿真)。 但实际要传,还是要传频带的波形信号。 但实际要传,还是要传频带的波形信号。 2. 为了模拟真实...
modulation. This part that QPSK modulation using matlab implementation is the heart of the program. Because Matlab is inadequate in the controllong of display, so visual c + + is used to implement the part of display. Therefore, this paper combines Matlab and visual c + + to achieve QPSK ...
