Abstract
In wireless communication, concept of parallel transmission of symbols is applied to achieve high throughput and better transmission quality. Orthogonal Frequency Division Multiplexing (OFDM) is one of the techniques for parallel transmission. The performance of uncoded orthogonal frequency division multiplexing (OFDM) over fading channels is generally improved by introducing some kind of channel coding. Coded OFDM (COFDM) has therefore been chosen for two recent new standards for broadcasting namely DAB and DVB-T. Different coding schemes for OFDM have been reported in the literature. In this paper our aim is to evaluate COFDM performance using block interleaver/Reed Solomon (RS) codes with convolution code and result is compared with uncoded OFDM. The performance parameter used for evaluation is BER with AWGN channel assumption. All other parameters used are as per IEEE 802.11a specification.
