On the diversity multiplexing tradeoff in a 4-user clustered Z-channel

We study a new interference channel called 4-user clustered Z-channel where 4 clusters consisting of two single-antenna nodes each construct a Z interference channel and the connected two clusters form a two-user interference channel. We analyze diversity multiplexing tradeoff (DMT) in this channel by joint decoding. We also propose a new interference… CONTINUE READING
