- W2061173320 abstract "In wireless communication, parallel transmission of symbols using multi carriers is applied to achieve high efficiency in terms of throughput and better transmission quality. In multipath environment the performance of orthogonal frequency division multiplexing is 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 environment. However high peak to average power ratio (PAPR) is a major demerit of OFDM system, it leads to increased complexity of circuit and reduced efficiency of RF amplifier. In this paper our aim is PAPR reduction of COFDM system using Discrete Hartley Transform (DHT) pre-coding and performance analysis in fading environment using BER as a performance index. COFDM system used here comply with IEEE 802.11a specifications and Reed Solomon (RS) codes along with convolution codes are used for serial concatenation and TURBO codes are used as parallel concatenation codes for channel coding purpose. Channel used for consideration is Rayleigh." @default.
