Abstract
In this paper, we propose a new channel estimation method for IEEE802.11a and HIPERLAN/2 wireless LANs. Based on the frequency coherence of the channel for wireless LANs, the absent frequency channel responds at virtual subcarriers and DC subcarrier are reconstructed by linear interpolation firstly, then channel estimation with time domain truncation is fulfilled. Simulation results show that the proposed method achieves a slightly better performance than the conventional iterative method and LS method while keeping less complexity.
