Performance Evaluation of OFDM system with and without RS coding

چکیده
Orthogonal frequency division multiplexing (OFDM) is a multi-carrier transmission technique that has been recently recognized as an excellent method for high speed bi-directional wired/wireless data communication. High capacity and variable bit rate information transmission with high bandwidth efficiency are just some of the requirements that the modern transceivers have to meet in order for a variety of new high quality services to be delivered to the customers. In this paper an overview of a OFDM (Orthogonal Frequency Division Multiplex) is given and performance is evaluated in terms of BER. We evaluate the performance of OFDM with and without RS coding under various modulation formats. Keywords— OFDM, BER, RS, WLAN.

متن کاملRS Turbo Coding for PAPR Reduction in Multiuser OFDM System
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 is obtained through a proper selection ...
