WebIn this paper, a systematic design of full-diversity STBC with low-complexity PIC group decoding is proposed. The proposed code design is featured as a group- orthogonal STBC by replacing every element of an Alamouti code matrix with an elementary matrix composed of multiple diagonal layers of coded symbols. WebApr 30, 2009 · Alamouti matrix based orthogonal STBC has been adopted in latest wireless standards (e.g. 802.11n, 3GPP LTE and WiMAX) for the reason that it is the only full-rate linear STBC code with a diversity gain of …

WebThe design [1] based on Alamouti’s two-antenna orthogonal code [2] generally yielded nongroup constellations. Using the tool of the group theory, Hughes [3] and Hochwald and Sweldens [4] designed DSTM for an arbitrary number M T of transmit antennas. An appealing feature of the group design is that matrix multiplication may be replaced by

Webwhere, differently to model (8.1), H m [n] is the N×Q complex flat-fading channel matrix at the mth subcarrier, the kth row of which, H k (m,n) contains the 1×Q vector of the channel gains for the kth user at the mth subcarrier. Also, in case of transmit beamforming, s m [n]=T m [n]x m [n], where T m [n] is a matrix of dimension Q×K that gathers the transmit …
