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. date: 2011 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-81255177831&partnerID=40&md5=acc66ab0d2cc96be7e58499486e5cec0 full_text_status: none publication: IAENG International Journal of Computer Science volume: 38 number: 4 pagerange: 314-319 refereed: TRUE issn: 1819656X citation: Baig, I. and Jeoti, V.
