Performance Analysis and PAPR Reduction of Coded OFDM (with RSCC and Turbo Coding) System Using Modified SLM, PTS and DHT Precoding in Fading Environments
In wireless communication, parallel transmission of symbols using multi carriers is used to achieve high efficiency in terms of throughput and better transmission quality. Orthogonal Frequency Division Multiplexing (OFDM) is one of the techniques for parallel transmission of information. In multipath environment the performance of orthogonal frequency division multiplexing degrades which can be improved by introducing some kind of channel coding. Coded OFDM (COFDM) is the new candidate for application such as Digital audio Broadcast (DAB) and Digital Video Broadcast (DVB-T) due to its better performance in fading environments.
