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

Résumé

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.
