Maximum-likelihood algorithm on the subchannel detection in forward links for multicarrier DS CDMA system

In this paper, we consider the subchannel detection problem in forward links for the multicarrier (MC) 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. The theoretical analysis and simulation results are presented. We also discuss the parameter selection problem for the length of the training sequence in the system model in Pingyi Fan et al. by using the proposed ML detection algorithm. The results show that the subchannel allocation schemes in Pingyi Fan et al. is feasible since only a few symbols overhead are required.
