High peak-to-average power ratio (PAPR) of the transmit signal is a major drawback of multicarrier (MC) transmission such as orthogonal frequency division multiplexing (OFDM) system. This paper presents a novel Reed-Solomon (RS) codes based MC transmission scheme for reduction of PAPR called RS Turbo coded OFDM system. The reduction of PAPR of OFDM signal(More)
An imminent mobile and telecommunication system must sustain not only accepted speech services however several other benefits such as wireless multimedia, small circuit switching and packet dependent data transmission are also being considered. For the realization of the above services with an attractive modulation procedure whose properties makes it(More)
Orthogonal frequency division multiplexing (OFDM) has several properties which make it an attractive modulation scheme for high speed wireless transmission links. In this paper, a novel power sharing technique is proposed for different users to improve the system performance. The proposed technique is based on use of variable amplitude of subcarriers (VAS).(More)
