[通讯编程] MYMIMO

文件来源: 我的毕设 仿真结果: 在窄带Rayleigh快衰落信道下几种检测方法的误码率性能比较 说 明: 参数tx,rx,L,EbN0可以根据需要更改。 tx,rx是收发天线数,根据需要取值就好了,一般研究2发2收和4发4收 EbN0是信噪比取值范围,根据需要选择吧。取得点多当然算得慢。 L影响结果的波动性和误码率所能达到的下限,L值取得越大图像越接近真实情况。如果 EbN0最大值有20dB那么误码率可以达到10负4次方建议L不低于10000。 使用方法: 把db.m和minnorm.m存进任意文件夹,然后打开matlab,File->Set Path->Add Folder加入 文件夹。在matlab中输入命令db即可 (2008-05-29, matlab, 5KB, 下载162次)
