A MATLAB scr ipt for the solution of location using UWB

介绍了数字通信中的QPSK调制解调的原理，通过用Matlab编写脚本程序对QPSK通信系统的发射和接收过程的具体实现进行模拟仿真，绘出信号在理想信道和加噪信道中模拟传输时的时域图，并对各模块进行了频谱分析，所得到的结果与 理论基本相符，对于理解QPSK系统的性能并在系统的实际应用上作进一步的设计，提供了有效的参考依据。 -The introduction was done with the principle of the QPSK modulation and demodulation

Increase the simulation time in the scr ipt, the simulated and theoretical results should converge • Use a pulse shaping filter at the transmitter • At the receiver, precede the discrete-time integrator with a multiplier by a replic
