Question: Consider a multi - user massive MIMO system consisting of L cells and K users in each cell. Let h _ ik ^ j~ CN

Consider a multi-user massive MIMO system consisting of L cells and K users in each cell. Let h_ik^j~ CN(0,\beta _ik^j I_M )be the channel from user k in i^thcell to BS in j^th cell. Show that
Var{h_jk^j ^2/(Eh_jk^j ^2)}=1/M
Var{((h_li^j)^H h_jk^j)/(Eh_li^j ^2 Eh_jk^j ^2)}=1/M
