— This paper presents a novel amalgam of Steered Space-Time Spreading (SSTS) and Orthogonal Frequency Division Multiple Access (OFDMA) designed for attaining both spatial diversi...
In this paper, we investigate the application of a unipolar Non-Coherent M-ary Orthogonal Keying (NC-MOK) for OFDM system that does not require channel estimation and compare its p...
— Recently Li and Xia have proposed a transmission scheme for wireless relay networks based on the Alamouti space time code and orthogonal frequency division multiplexing to comb...
Abstract-In fast time varying systems, the problem of acquiring the channel coefficients required for symbol decoding commonly arises. A method of resolving this problem is the use...
