Abstract

In this paper, we propose a type of beamforming technique for orthogonal frequency division multiplexing (OFDM) based wireless personal area networks (WPANs) based on blocks idea. In order to compromise between performance and computational complexity, the proposed scheme divides all the subcarriers into blocks, then utilizes the similarity of adjacent blocks, and decides whether to carry out first order perturbation compensation (FOPC) or eigenvalue based beamforming (EBB) algorithm. Simulation results indicate that FOPC-EBB algorithm with blocking operation can achieve better effect in reducing the complexity.
