A interferência de acesso múltiplo (MAI) devido a muitos usuários simultâneos é o principal fator que limita o desempenho do sistema DS-CDMA. A detecção multiusuário é um método para evitar a degradação do desempenho devido ao MAI. Propomos um método cego de detecção multiusuário baseado no algoritmo que consiste em um processo de decodificação em dois estágios, ou seja, módulo constante linearmente restrito (LCCM) e mínimos quadrados iterativos (ILS). As simulações computacionais confirmaram que o algoritmo é resistente ao quase-longe e que o método proposto é eficaz na aplicação aos canais com desvanecimento lento.

Abstract: Multiple access interference (MAI) due to many simultaneous users is the main factor that limits the performance of DS-CDMA system. Multiuser detection is a method to avoid performance degradation due to MAI. We propose a blind multiuser detection method based on the algorithm consisting of two-stage decoding process, i.e., linearly constrained constant modulus (LCCM) and iterative least squares (ILS). The computer simulations confirmed that the algorithm is near-far resistant and that the proposed method is effective in the application to the slow fading channels.
