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


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)
