Abstract

We consider the channel estimation for the subband orthogonal frequency-division multiple-access (OFDMA) uplink. The channel for each subband is modeled by combing the linear and Fourier basis-expansion functions. Based on this mode, a two-dimensional interpolation approach is proposed for the channel estimation, which is carefully investigated in terms of estimation error and pilot placement.
