Design and Performance Analysis of Distributed Space Time Coding Schemes for Cooperative Wireless Networks
ii PhD Thesis by Gbenga Owojaiye University of Hertfordshire, Hatfield, Herts. AL10 9AB, United Kingdom Abstract In this thesis, space-time block codes originally developed for multiple antenna systems are extended to cooperative multi-hop networks. The designs are applicable to any wireless network setting especially cellular, adhoc and sensor networks where space limitations preclude the use ...
متن کاملPerformance Analysis of Space Time Coding
AbstractMost work on wireless communications had focused on having an antenna array at only one end of the wireless link — usually at the receiver. Seminal papers by Gerard J. Foschini and Michael J. Gans, Foschini and Emre Telatar enlarged the scope of wireless communication possibilities by showing that for the highly-scattering environment substantial capacity gains are enabled when antenna ...
متن کاملScalable layered space-time codes for wireless communications: performance analysis and design criteria
− Dual antenna-array systems provide very high capacity compared to single antenna systems in a Rayleigh fading environment. If the transmitter does not have channel state information, to utilize this high capacity, space-time codes must be employed. The diagonally layered space-time (DLST) architecture is a structure that is capable of providing a high data rate for a low decoding complexity. ...
متن کاملOn performance analysis and design criteria for trellis coded differential unitary space-time modulation
In this paper, we propose the trellis coded differential unitary space-time modulation (TC-DUSTM) and present the derivation of the formulae of the pairwise error-event probability (PEP) and the bit error probability (BEP) for this scheme. We found that in a multi-input multi-output (MIMO) system with M transmit and N receive antennas, apart from the diversity gain of MN , a coding gain of min ...
متن کاملDistributed space-time coding for cooperative networks
In this report we show how proper cooperation among radio nodes may provide diversity gain, also for single antenna systems. We consider first the connectivity of a wireless network and show how it can benefit from cooperation. Then, we consider some specific forms of cooperations, based on distributed space-time coding, in both single and multi-user contexts. Finally, we pay a special attentio...
