O algoritmo de módulo constante (CMA) do array adaptativo foi desenvolvido para suprimir a interferência co-canal e a interferência intersimbólica em comunicações móveis. Neste artigo, um novo CMA para o híbrido de matriz adaptativa e equalizador (HAE) é proposto para combater os problemas de graus de liberdade insuficientes e interferências multipercurso de feixe principal. O HAE com CMA utiliza a propriedade de módulo constante para o sinal de saída do HAE para ajustar os vetores de peso da matriz e do equalizador simultaneamente. As interferências co-canal podem ser canceladas pelo array e as interferências multipercurso podem ser removidas pelo array ou pelo equalizador seguindo o array no HAE. Portanto, o conjunto no HAE com CMA pode necessitar de um número menor de elementos do que o exigido pelo conjunto CMA, o que cancela tanto as interferências co-canal como as interferências multipercurso. Além disso, a presença de interferências de múltiplos caminhos do feixe principal, que podem degradar seriamente o desempenho do arranjo CMA, tem muito menos efeito no HAE com CMA, uma vez que pode ser suprimida pelo equalizador em vez do arranjo. Os resultados da simulação são apresentados para demonstrar os méritos do CMA para o AEH.

Abstract: The constant modulus algorithm (CMA) of the adaptive array has been developed for suppressing the co-channel interference and the intersymbol interference in mobile communications. In this paper a novel CMA for the hybrid of the adaptive array and equalizer (HAE) is proposed to combat the problems of insufficient degrees of freedom and mainbeam multipath interferers. The HAE with CMA utilizes the constant modulus property for the output signal of the HAE to adjust the weight vectors of the array and equalizer simultaneously. The co-channel interferers can be canceled by the array and the multipath interferers can be removed by the array or the equalizer following the array in the HAE. Therefore, the array in the HAE with CMA may need less number of elements than that required by the CMA array which cancels both the co-channel interferers and multipath interferers. Besides, the presence of the mainbeam multipath interferers, which may seriously degrade the performance of the CMA array, has much less effect on the HAE with CMA since it can be suppressed by the equalizer instead of the array. Simulation results are presented to demonstrate the merits of the CMA for the HAE.

AB - The constant modulus algorithm (CMA) of the adaptive array has been developed for suppressing the co-channel interference and the intersymbol interference in mobile communications. In this paper a novel CMA for the hybrid of the adaptive array and equalizer (HAE) is proposed to combat the problems of insufficient degrees of freedom and mainbeam multipath interferers. The HAE with CMA utilizes the constant modulus property for the output signal of the HAE to adjust the weight vectors of the array and equalizer simultaneously. The co-channel interferers can be canceled by the array and the multipath interferers can be removed by the array or the equalizer following the array in the HAE. Therefore, the array in the HAE with CMA may need less number of elements than that required by the CMA array which cancels both the co-channel interferers and multipath interferers. Besides, the presence of the mainbeam multipath interferers, which may seriously degrade the performance of the CMA array, has much less effect on the HAE with CMA since it can be suppressed by the equalizer instead of the array. Simulation results are presented to demonstrate the merits of the CMA for the HAE.
