Para aumentar a taxa de transmissão sem expansão da largura de banda, a técnica de múltiplas entradas e múltiplas saídas (MIMO) tem atraído muita atenção recentemente. A capacidade do canal MIMO em um sistema celular é afetada pela interferência de células co-canais vizinhas. Neste artigo, apresentamos a capacidade do canal celular e avaliamos sua capacidade de interrupção, levando em consideração o fator de reutilização de frequência, o expoente de perda de caminho, o desvio padrão da perda de sombreamento e a potência de transmissão de uma estação base (BS). Além disso, comparamos a capacidade do canal de downlink MIMO celular com aquelas de outras técnicas de transmissão de múltiplas antenas, como entrada única e saída múltipla (SIMO) e saída única de entrada múltipla codificada em bloco de espaço-tempo (STBC-MISO). Mostramos que o fator ótimo de reutilização de frequência F que maximiza a capacidade de interrupção de 10% é 3 e as capacidades de interrupção de 50% e 90% é 1, independentemente do tipo de técnica de transmissão de múltiplas antenas, onde qA % de capacidade de interrupção é definida como a capacidade do canal que fornece uma probabilidade de interrupção de q%. Mostramos também que a capacidade do canal MIMO celular é sempre maior que a do SIMO e STBC-MISO.

Abstract: To increase the transmission rate without bandwidth expansion, the multiple-input multiple-output (MIMO) technique has recently been attracting much attention. The MIMO channel capacity in a cellular system is affected by the interference from neighboring co-channel cells. In this paper, we introduce the cellular channel capacity and evaluate its outage capacity, taking into account the frequency-reuse factor, path loss exponent, standard deviation of shadowing loss, and transmission power of a base station (BS). Furthermore, we compare the cellular MIMO downlink channel capacity with those of other multi-antenna transmission techniques such as single-input multiple-output (SIMO) and space-time block coded multiple-input single-output (STBC-MISO). We show that the optimum frequency-reuse factor F that maximizes 10%-outage capacity is 3 and both 50%- and 90%-outage capacities is 1 irrespective of the type of multi-antenna transmission technique, where q%-outage capacity is defined as the channel capacity that gives an outage probability of q%. We also show that the cellular MIMO channel capacity is always higher than those of SIMO and STBC-MISO.
