Abstract :
This paper is on the design of practical distributed space-time codes for wireless relay networks. The amplify-and-forward (AF) scheme is used in a way that each relay transmits a scaled version of the linear combination of the received symbols. We propose distributed GABBA codes, which is generalized to any number of relays and independent of modulation type. Using linear orthogonal decoding in the destination makes it feasible to employ large number of potential relays to improve diversity order.
