QAMXIANGP
本程序仿真了16QAM信号的载波相偏估计的HOS算法，整个算法实现分为（1）模拟发送端发送16QAM信号；（2）加入相偏来模拟通过信道后有相偏的测试信号；（3）利用HOS算法进行相偏估计与纠正；（4）输出星座图。(This procedure simulated a 16QAM signal carrier phase offset estimate of the HOS algorithm, the algorithm is divided into (1) analog transmitter to send 16QAM signal (2) by the inclusion of partial to simulate the channel after the phase offset of the test signal (3 ) algorithm using HOS phase offset estimate and correction (4) output constellation.)

rakereceive_kron
本程序仿真了AWGN信道下，采用DS扩频对bpsk信号的影响，扩频码采用walsh码，扩频因子16；
接收端进行rake接收，然后分集合并，比较了三种分集方式对误码率的影响
从图像可以看出在扩频因子较高的情况下，最大比值合并与等增益合并性能相近(This program simulates the AWGN channel, using DS spread spectrum signal for bpsk influence spreading code using walsh code spreading factor 16
Rake receiver receiving end, and diversity combining, diversity compares three methods on the bit error rate of
As can be seen from the image in the case of higher spreading factor, the maximum ratio combining and equal gain combining similar performance)
