Ultra-Fast Blind Equalization for OFDM: Principle and Steps Towards Implementation

Abstract : Blind equalization allows the transmitted signals to maximize their spectral efficiency, but it is limited by the convergence time of used algorithms. In this paper, the authors propose a new frequency blind equalization method for orthogonal frequency division multiplexing (OFDM), which drastically reduces the transient state delay of the algorithm’s convergence process. It consists of reusing a proper number of received OFDM symbols that have been stored in a memory. Simulations results reveal that a quasi-instantaneous equalization process can be achieved. In addition, the implementation issues are discussed in this paper.
