Abstract

We present closed-form expressions for the single-user capacity over slow nonselective correlated Rayleigh fading channels having equal branch powers and the same correlation between any pair of branches. Maximal ratio combining (MRC) is used and three adaptive transmission schemes are analyzed: (1) optimal simultaneous power and rate adaptation, (2) optimal rate adaptation with constant transmit power, (3) channel inversion with fixed rate
