Precoding and decoding in the MIMO interference channel for discrete constellation
2013 IEEE 24th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC)
This paper addresses the problem of decoding and precoding in the K-user MIMO interference channels. At the receiver side, a joint decoding of the interference and the desired signal is able to improve the receive diversity order. At the transmitter side, we introduce a joint linear precoding design that maximizes the joint cut-off rate, known as a tight lower bound on the joint mutual information for high signal-to-noise ratio (SNR). We also derive a closed-form solution of the precodingdoi:10.1109/pimrc.2013.6666312 dblp:conf/pimrc/FadlallahKAAP13 fatcat:tzrantprxjeafizih4zim4bema
