摘要
Abstract
In order to solve the high PAPR ( Peak to Average Power Ration ) problem in FBMC ( Filter Bank MmultiCarrier ) system, based on the prototype filter and its polyphase structure in FBMC system, a solution is proposed to reduce PAPR in FBMC system using pulse shaping technique, which borrows ideas from solutions to reduce PAPR in OFDM ( Orthogonal Frequency Division Multiplexing ) system. The cyclic shifting is implemented in time-domain by adding weighting in frequency-domain after S/P ( Serial to Parallel ) in synthesis filer banks, thereby the reduction of PAPR is accomplished. The simulation results indicate that PAPR is obviously reduced after importing PS in FBMC system.关键词
