Abstract :
In this paper, we present a low complexity frequency-domain turbo equalization algorithm for single-carrier system without cyclic prefix. Comparing with the traditional time-domain turbo equalization, the proposed algorithm can be implemented in the frequency domain with fast Fourier transform (FFT), and it does not involve matrix inversion. Simulation results show that the proposed algorithm also exhibits good performance.
