description: This paper presents a novel precoding based hybrid multi-carrier/single-carrier (MC/SC) uplink radio access system for layered orthogonal frequency division multiple access (Layered-OFDMA) of long-term-evolution advanced (LTE-Advanced). Generalized-Chirp-like (GCL) precoder is implemented before subcarrier mapping and IFFT to reduce the high peak-to-average power ratio (PAPR) of MC uplink system. Conventional localized single carrier frequency division multiple access (LFDMA) is also implemented to support all the functionalities provided in release 8 LTE. Extensive computer simulations have been performed to analyze the PAPR of precoding based MC/SC uplink system. The computer simulations show that the PAPR of GCL precoded MC signals approaches in the order of SC signals. Additionally, GCL precoded MC system also take the advantage of the frequency variations of the communication channel and can also offer substantial performance gain in fading multipath channels.
