Therefore, the increased frequency diversity in the system due to spreading improves bit error rate performance in the presence of frequency selective fading channels. In addition to that the new scheme improves symbol detection due to the inherited coding in the spreading technique. Simulation results show significant improvement in BER performance for the proposed system compared with conventional OFDM. © 2011 IEEE.enPermission to reuse abstract has been secured from Institute of Electrical and Electronics Engineers Inc.Block processingDetectionError control codingOFDMPermutation spreadingBit error rate (BER) performanceFading channelsFrequency allocationFrequency selective fadingOrthogonal functionsOrthogonal frequency division multiplexingConference PaperCopyright : 2011 IEEE.
