Low PAPR by Weighted OFDM

Devi Radhakrishnan, Nijina A


Abstract: Orthogonal frequency division multiplexing is a technique which is used in next generation mobile radio communication system. OFDM signals bandwidth efficiency is increased since here serial data is multiplexed in to large number of orthogonal sub channels. The disadvantage of OFDM system is that it has got high PAPR. In this paper to overcome this weighted orthogonal frequency division multiplexing (OFDM) signal is used without causing any distortion in weight removing at receiver side. The performance is analyzed through simulations. According to numerical results obtained PAPR of proposed scheme is reduced compared to convolution method and BER performance is compared to clipping and filtering method and PTS technique


Keywords: PAPR, Clipping and filtering, orthogonal frequency division multiplexing, PTS, BER
