说明：  generate prbs pattern

说明：  完成对cmw500测试仪器的程控及初始化操作(Novice is currently in the learning stage. CMW500 GSM non-signaling test program example, including initialization)

文档中介绍首先介绍了多用户MIMO模型，以及LTE中的多用户MIMO方案，通过仿真分析总结出当用户数较少时，在高信噪比条件下，ZF方案的系统吞吐量性能明显优于PU2RC方案。(Document describes first introduced a model of a multi-user MIMO, and LTE multi-user MIMO scheme, by simulation analysis summed up when the number of users is small, at high SNR conditions, the system throughput performance of the ZF program superior PU2RC program.)

说明：  在实际的调谐解调电路中，采用的是非相干载波解调，本振信号与发射端的载波信号存在频率偏差和相位抖动，因而解调出来的模拟I、Q基带信号是带有载波误差的信号。这样的模拟基带信号即使采用定时准确的时钟进行取样判决，得到的数字信号也不是原来发射端的调制信号，误差的积累将导致抽样判决后的误码率增大，因此数字QPSK解调电路要对载波误差进行补偿，减少非相干载波解调带来的影响。(In the actual tuning and demodulating circuit, non-coherent carrier demodulation is adopted, and the frequency deviation and phase jitter of the local oscillator signal and the carrier signal of the transmitting end are present, and thus the demodulated analog I and Q baseband signals are signals with carrier error.)

针对盲模拟调制信号的自动识别算法，利用了盲信号识别中常用的gamma、ap、dp、P等参数，并附送dsb、lsb、usb、am、fm信号的生成程序(Automatic analogue modulation recognition using MATLAB. There is also a function to generate dsb,lsb,usb,am,fm signal)
