Maximising the Average Spectral Efficiency of Dual-Branch MIMO Systems with Discrete Rate Adaptation

Abstract

The capacity of MIMO systems with perfect transmitter and receiver channel state information (CSI) can be attained by decoupling the MIMO channel into a set of independent subchannels, and distributing the power among these subchannels in accordance with the water-fitting solution. Implementation of this scheme on a time-varying channel requires however… (More)
