OFDM Based Power Line Communication Intensification Using RSC Coding with Adaptive Noise Compensator

In this paper ,we propose a Recursive systematic convolutional coding combined with adaptive noise compensation to minimize the interference and path effects with better performance than the turbo codes at very low bit error rate and high coding rate. RSC encoder, decoder, mapper, DE mapper are inserting in this system and pilot insertion block for enhance the preliminary estimation of Orthogonal Frequency Division Multiplexing modulation. Compensator is based on impulse bursts estimation using a new clipping and blanking function, estimation of Signal to noise ratio and Peak to average power ratio. Compare to the existing system, The proposed system gives better performance at high coding rate with less latency.
