摘要：

In this paper, we address the topic of multi-user channel estimation in a wireless system that combines Orthogonal Frequency Division Multiplex transmission and Adaptive Antenna Arrays, for increased spectral use and efficiency. Two current techniques for slowly varying channels are reviewed: a Least Squares estimator and a simplified low-complexity estimator. The proposed technique of Constrained Inverse Deconvolution (CID) is presented next. Analysis of simulation results show that the performance of the CID method can equal that of the LS technique with less computational complexity.
