Cooperative space-time codes with network coding [PDF]
EURASIP Journal on Wireless Communications and Networking, 2012 Because of the gains like diversity, throughput, and the coverage extension provided by the multiple-input multiple-out (MIMO) systems, it has been part of the various wireless communications standards. However, to reap the benefits offered by MIMO systems in size-constrained nodes, used in wireless communications, has been a challenging issue.

Generalized PSK in Space–Time Coding [PDF]
IEEE Transactions on Communications, 2005 A wireless communication system using multiple antennas promises reliable transmission under Rayleigh flat fading assumptions. Design criteria and practical schemes have been presented for both coherent and non-coherent communication channels. In this paper we generalize one dimensional phase shift keying (PSK) signals and introduce space time ...
