- W2380974815 abstract "The Over-saturated Wavelet Packet Division Multiple Access (OWPDMA) is introduced to improve the capacity of wireless communication system. The lowest scale OWPDMA code set is presented, in which wavelet packet basis functions with the lower scales, i.e. codes on the nodes closing to the root in the tree, are selected as OWPDMA over-saturated codes. The low complexity optimal joint detection for tree-structured multiple access system is used as its multi-user detector (MUD). Computer simulation results in AWGN channel and single path Rayleigh fading channel demonstrate that the lowest scale OWPDMA code set provides larger capacity than orthogonal code set does, and has the acceptable performance weakly inferior to that of orthogonal code set. Its MUD method reduces the complexity from exponential to low-order-polynomial in the number of users." @default.
