— This paper considers receiver design for Space Time Block Coded MIMO OFDM transmission over frequency selective time-variant channels. The receiver employs the expectation-maximization (EM) algorithm for joint channel and data recovery. It makes collective use of the data and channel constraints that characterize the communication problem. The data(More)
— In this paper we study the downlink spectral efficiency of a wireless network using Orthogonal Frequency Division Multiple Access (OFDMA), Multiple Input Multiple Output (MIMO) antenna systems and Opportunistic Scheduling (OS) techniques. The main purpose of the study is to understand how these techniques interact and influence the spectral efficiency of(More)
