Progressive linear precoder optimization for MIMO packet retransmissions exploiting channel covariance information

Sun, H; SHi, Z; Zhao, C.; Manton, Jonathan; Ding, Z.


This work investigates the design of linear precoders for ARQ packet retransmissions in Multi-Input Multi-Output (MIMO) systems. We consider transmitter precoder design based on partial MIMO channel information in the form of their covariance feedback. Our objective is to maximize the ergodic mutual information provided by multiple (re)transmissions of a packet subject to transmission power constraint. We propose a set of near-optimal successive linear ARQ precoders for flat fading MIMO...[Show more]
