Power Controlled MIMO-MAC Capacity With Diversity Combining

We consider capacity analysis of power controlled multiple-input multiple-output (MIMO) systems for multiple-access channels (MAC) where receivers are equipped with diversity combiners such as maximum ratio combiner (MRC), equal gain combiner (EGC) and selection combiners (SC). Moreover, it is shown...

Description
Summary:We consider capacity analysis of power controlled multiple-input multiple-output (MIMO) systems for multiple-access channels (MAC) where receivers are equipped with diversity combiners such as maximum ratio combiner (MRC), equal gain combiner (EGC) and selection combiners (SC). Moreover, it is shown here by simulations that at high signal-to-noise ratios (SNR) cut-off parameter, gamma, converges to 1/K, where K is the number of users. Numerical results for frequency-flat Rayleigh fading channels with a specific number of antennas for each user using different receiver combining techniques are shown in ergodic capacity-user numbers and ergodic capacity-SNR graphs and the results are commented
