Transfer power allocation of WCDMA synchronization channel and common pilot channel
Zhou Chunhui, Meng Lin, Xibin Xu, Ming Zhao, Yan Yao · 2002
This paper presents a performance analysis of WCDMA synchronization channel (SCH) and gives the optimal transfer power allocation scheme of SCH and common pilot channel (CPICH) to achieve best cell search performance. The AWGN channel, noncoherent detection and multi-slot, multi-frame accumulation are employed in performance simulation. One considerable scheme is P/sub SSCH/:P/sub PSCH/=0.25:0.75 and P/sub CPICH/:P/sub SCH/=0.35:0.65, under which the UE can finish cell search in 160 ms with satisfactory performance.
