A ZADOFF-CHU MATRIX TRANSFORM PRECODING BASED LOCALIZED-OFDMA UPLINK SYSTEM: A PAPR ANALYSIS WITH RRC PULSE SHAPING

High peak-to-average power ratio (PAPR) is one of the major drawbacks in the orthogonal frequency division multiple access (OFDMA) systems. In this paper, we present a zadoff-chu matrix transform (ZCMT) precoding based localized OFDMA uplink system with improved PAPR. The proposed system is based on...
