Este artigo analisa a capacidade ergódica do canal MIMO multi-keyhole, assumindo que a informação do estado do canal (CSI) está disponível apenas no receptor. Primeiro derivamos novas expressões de forma fechada para a função de densidade de probabilidade marginal (pdf) do autovalor único não ordenado, bem como a pdf conjunta dos autovalores ordenados da matriz do canal em uma estrutura simples e geral. Com esses resultados estatísticos, apresentamos então uma expressão exata de forma fechada para a capacidade ergódica. Analisamos limites rígidos sobre a capacidade exata e propomos um novo limite inferior restrito. Também investigamos o desempenho da capacidade assintótica em regimes de baixa relação sinal-ruído (SNR) e alta SNR para obter mais informações. Todos os nossos resultados se aplicam a um número arbitrário de buracos de fechadura e antenas. Simulações numéricas são apresentadas para validar nossa análise teórica.

Abstract: This paper analyzes the ergodic capacity of the MIMO multi-keyhole channel, assuming that the channel state information (CSI) is available only at the receiver. We first derive new closed-form expressions for marginal probability density function (pdf) of the single unordered eigenvalue as well as joint pdf of ordered eigenvalues of the channel matrix in a simple and general framework. With these statistical results, we then present an exact closed-form expression for the ergodic capacity. We analyze tight bounds on the exact capacity and propose a new tight lower bound. We also investigate the asymptotic capacity performances in low-signal-to-noise-ratio (SNR) and high-SNR regimes to gain further insights. All our results apply for arbitrary number of keyholes and antennas. Numerical simulations are presented to validate our theoretical analysis.
