    垂直分层编码ZF检测算法程序代码问题,此程序是在调制方式为QPSK或4QAM下,未编码的V-BLAST系统 计算噪声功率时,信号的功率要用总的接收信号的功率.每根接收天线上的噪声功率是相同的.同时总的信号能量归一化,每根天线上发送的信号能量是总的发 送能量的1/Nt,其中Nt是发送天线数, 改变发送天线Nt和接收天线数目Mt,可以比较QPSK和4QAM时4发4收,4发6收,8发8收,8发12收等多发多收的情况 (Vertical stratification coding ZF detection algorithm program code, the process is in a way for QPSK or 4 QAM, not coding V-BLAST system Calculating noise power, the power of the signal with general received signal power. Each root receiving antenna on the noise power are the same. And general signal energy normalization, each blade on the signal energy send antenna is overall hair Send energy 1/Nt, of which is transmitting antenna Nt number, change the transmitting antenna Nt and receiving antenna number Mt, can compare QPSK QAM and 4 when the hair 4 4, 4 hair and accept, eight hair 8 accept, eight hair 12 accept etc multiple collect more of the situation )
