Abstract :
A novel blind algorithm is developed to mitigate the residual interblock interference (RIBI) for orthogonal frequency division multiplexing (OFDM) systems. The algorithm is based on the RIBI cancellation and cyclic structure recovery. Simulation shows that the proposed algorithm can effectively mitigate RIBI and has a low computation complexity.
