Bit-Allocation Strategies for MIMO F ading Channels with Channel Knowledge at Transmitter

Abstract

The singular-value decomposition can be used to transform a MIMO fading channel into an equivalent bank of scalar subchannels, also known as eigenbeamforming or closed-loop MIMO, provided that the transmitter knows the channel. We consider the problem of allocating bits to subchannels after such processing, and propose simple strategies with near-optimal… (More)
