Review on Doubling the Rate of SEFDM Systems using Hilbert Pairs
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2021, Vol 5, Issue 4
Abstract
A novel multi carrier technique for spectrally efficient frequency division multiplexing SEFDM system for improving the spectral efficiency is discussed. A Hilbert pair is utilized as pulse shaping filters. At the the Hilbert pulse pair is generated using the square root raised cosine pulse and an equivalent matched filter configuration is utilized to generate the Hilbert pair at receiver. Simulations with different values of compression factor of the SEFDM signals were carried out to verify the data rate gain of the proposed system. The proposed system has no degradation in bit error rate performance with the data rate doubled relative to conventional SEFDM system. For system using turbo coding, there is significant BER improvement compared to uncoded transmission.
