qpsk在高斯信道下的仿真，包括误码率和仿真图(Simulation of QPSK in Gaussian channel)

This project demonstrates OFDM with adaptive modulation applied to Multiple-Input Multiple- Output (MIMO) systems. The analysis and simulation is considered in two stages. The rst stage involves the application of a variable-rate variable-power MQAM technique for a Single-Input Single-Output (SISO) OFDM system. The second stage applies adaptive modulation to a general MIMO system by making use of the Singular Value Decomposition to separate the MIMO channel into parallel subchannels.

高斯一阶导数生成的UWB单脉冲信号，脉冲宽度为0.5ns(Gaussian first derivative monopulse generated UWB signal, pulse width of 0.5ns)

PSK通信信号盲解调测试程序，final1_1和final1_2为两种不同的产生PSK通信信号的程序，final2_1预估计载波频率，final2_2预估计码元速率，final3进行载波同步，final4进行码元同步，进而解调出原信号。(PSK Blind Demodulation)
