Vários métodos de matriz de sub-bandas foram propostos como meios úteis para realizar a equalização espaço-temporal conjunta em comunicações móveis digitais. Esses métodos podem ser aplicados para mitigar problemas causados pela interferência entre símbolos (ISI) e interferência co-canal (CCI). Os métodos de matriz de subbandas propostos até agora podem ser classificados em dois esquemas principais: (1) um esquema de realimentação centralizado e (2) um esquema de realimentação localizada. Neste artigo, propomos matrizes de sub-bandas com esquema de realimentação parcial, que generalizam os dois esquemas de realimentação acima. A principal contribuição deste artigo é derivar o desempenho do erro quadrático médio (MSE) em estado estacionário de matrizes de sub-bandas que implementam esses três esquemas de feedback diferentes. Ao contrário do esquema de realimentação centralizado, que pode ser projetado para fornecer desempenho de equalização ideal, os arranjos de sub-bandas com esquemas de realimentação localizada e parcial são, em geral, abaixo do ideal. O desempenho destes dois esquemas de feedback subótimo depende das características do canal, dos bancos de filtros empregados e do número de sub-bandas.

Abstract: Several subband array methods have been proposed as useful means to perform joint spatio-temporal equalization in digital mobile communications. These methods can be applied to mitigate problems caused by the inter-symbol interference (ISI) and co-channel interference (CCI). The subband array methods proposed so far can be classified into two major schemes: (1) a centralized feedback scheme and (2) a localized feedback scheme. In this paper, we propose subband arrays with partial feedback scheme, which generalize the above two feedback schemes. The main contribution of this paper is to derive the steady-state mean square error (MSE) performance of subband arrays implementing these three different feedback schemes. Unlike the centralized feedback scheme which can be designed to provide the optimum equalization performance, the subband arrays with localized and partial feedback schemes are in general suboptimal. The performance of these two suboptimal feedback schemes depends on the channel characteristics, the filter banks employed, and the number of subbands.
