Abstract

The distribution of the received signal power Â¿ of a multiple-input multiple-output system, with the associated 2 Ã— 2 complex Wishart matrix having n degrees of freedom, is investigated under the channel inversion power allocation scheme. Exact closed-form expressions are derived for the probability density function and the cumulative distribution function of Â¿. The analysis covers systems with transmit-receive antennas {N_t,N_r| min(N_t, N_r) = 2, max(N_t, N_r) Â¿ 2}, and independent and identically distributed Rayleigh fading links between each antenna pair. We derive (i) the distribution of Shannon capacity of the multiple-input multiple-output channel (ii) average symbol error rate for a class of modulation schemes that includes Binary Phase Shift Keying.
