| Abstract: | The detection of the secondary synchronization channel(S-SCH) in the 3GPP(3rd generation partnership project) long term evolution(LTE) downlink system is investigated in this paper.In order to reduce the high computational complexity of the conventional maximum likelihood sequence detection(MLSD) algorithm,a scheme of low complexity is proposed.By utilizing special structures of the S-SCH sequence the number of the candidate S-SCH sequences is reduced.By applying fast Hadamard transformation,the computation... |
