A new inter-carrier interference self-cancellation mapping scheme over fast time-varying fading channels
A new inter-carrier interference self-cancellation method with the data symbol mapping scheme of differential grouping weighted symmetry data-conjugate is studied and proposed to raise the bandwidth efficiency and further improve the system performance over fast time-varying fading channels. Comparing with the other existing self-cancellation methods, the proposed scheme can not only maintain the same bandwidth efficiency as the original orthogonal frequency division multiplexing system, but also show a better performance on carrier-to-interference ratio and bit error rate according to the final simulation results and performance analysis.
