Neste artigo, consideramos o problema de detecção de subcanais em links diretos para o sistema DS-CDMA multiportadora quando algumas políticas diferentes de alocação de subcanais são usadas. Um algoritmo de decisão de subcanal ideal é proposto com base no critério de máxima verossimilhança (ML). Análise teórica e resultados de simulação são apresentados. Além disso, discutimos o problema de seleção de parâmetros no comprimento das sequências de treinamento no esquema de alocação de subcanais em [8],[12] usando o algoritmo de detecção de ML proposto. Os resultados mostram que o esquema de alocação de subcanais em [8],[12] é viável, uma vez que apenas alguns símbolos são necessários.

Abstract: In this paper, we consider the subchannel detection problem in forward links for the multicarrier DS-CDMA system when some different subchannel allocation policies are used. An optimal subchannel decision algorithm is proposed based on the maximum-likelihood (ML) criterion. Theoretical analysis and simulation results are presented. Furthermore, we discuss the parameter selection problem on the length of the training sequences in the subchannel allocation scheme in [8],[12] by using the proposed ML detection algorithm. The results show that the subchannel allocation scheme in [8],[12] is feasible since only a few symbols overhead is required.
