[問題] ML Equalizer 的問題
是這樣的小弟是參考這篇文章去做 ML Equalizer
http://www.dsplog.com/2008/12/14/mimo-ml-equalization/
他的例子是用 BPSK 所以她的J就有四種組合，但是有一個點一直很困惑就是他的J算出來
都是一個2x1的矩陣，這要是要怎麼選哪個是minimum...還請各位幫我解惑一下>_<
PS.
看他的做法 hat x1 hat x2是用 +1 -1 下去組合 如果選到的是+1 +1 那組 就代表BPSK
的 1 1 如果是 -1 -1 那組 就是代表BPSK的 0 0 以此類推，想在這邊請問一下如果今天
我要用 QPSK 是不是就接用 1+1i 1-1i -1+1i -1-1i 這四個值去當 hat x1 hat x2
然後就會有16個J去做比大小這樣??
