consider a $2$x$1$ mimo system. let y$[1]=0\mathrm{.}13+$j$0\mathrm{.}5,$ y$[2]=0\mathrm{.}9+$j$1\mathrm{.}2$ be the received symbol over two time slots. assue : it$)$ the transmitted symbol are bpsk with amplitudes a$1=+1$ and ao$=-1.($ii$)$ symbols were transmitted using alammati scheme $,($iii$)$ the channel gainar h$1=0.8+$j$0\mathrm{.}1,$ h$2=-0.75+$j$0.3,$ and receives knows the channel gains $,$ and $($iv$)$ noise ~ CN$(0,1).$ perform ml detectio and find the transmitted symbols
