METHODS AND SYSTEMS FOR FOURIER-QUADRATIC BASIS CHANNEL ESTIMATION IN OFDMA SYSTEMS
摘要
<p>Certain embodiments of the present disclosure relate to a Fourier-Quadratic (FQ) method for channel estimation that may help improve error rate performance of existing techniques, with only moderate increase in computational complexity. The proposed FQ scheme according to certain embodiments may provide a viable solution to the difficult channel estimation problem encountered in the Vehicular B channel with a long delay spread. Furthermore, a robustness of the proposed FQ channel estimation scheme to accommodate errors in a channel delay profile and to errors in a channel power profile is demonstrated through simulations.</p>
