Abstract
The matrix representation of the signal model of MIMO-OFDM systems, which clearly describes the relation of signals in frequency domain and time domain and expressing operations like adding CP and removing CP as matrix product. Our channel estimation method differs in its ability to estimate fast time-varying wireless channel since pilot tones are inserted into each OFDM block, and in its explicit relation with space-frequency code design which can benefit the channel estimation in return. Then the simple LS algorithm can be used to solve the estimation problem, provided that the noise term in the quasilinear form is Gaussian. In this paper, the ML algorithm can be directly utilized to estimate the target location since the probability density function of the observation data is known with our assumption. Finally, the extensive simulation studies have demonstrated the effectiveness of our proposed algorithm. We proposed a low complexity algorithm for equalization, which uses the estimated BEM coefficients directly without creating the channel matrix and equalization method require O (K log K) in operations and O (K) in memory.
