Abstract :
This paper presents combination of optimal power adaptation and adaptive modulation for MIMO systems with imperfect channel state information (CSI). Proposed algorithm is designed to enable high-reliable transmission with as much possible capacity, convenient for high data rate FEC systems. Effect of use of Reed-Solomon code in the case of imperfect CSI is also considered.
