ABSTRACT
A new coordinate interleaved user cooperation scheme for distributed Alamouti space-time block code (DSTBC) is presented. When coordinate interleaved symbols are transmitted using DSTBC, a diversity order of four is reached at the destination for perfect cooperation (PC) of two users. A selective cooperation (SC) approach is proposed to prevent detrimental effect of the interuser channel. Error performance of the proposed coordinate interleaved DSTBC (CI-DSTBC) for PC and SC in noisy interuser channel is evaluated by computer simulations for QPSK modulation and its superiority compared to the corresponding counterparts given in the literature is brought out.

Outage Probability Analysis of Three-User Reed---Solomon Coded Cooperation Scheme for Wireless Slow Fading Channel
In a coded cooperation scheme, the relay must decode and re-encode data. This process needs to be completed rapidly. Therefore, a simple channel coding/decoding scheme that requires low computational loads is needed. Reed---Solomon (RS) codes are simple,...
Multigroup ML decodable collocated and distributed space-time block codes
In this paper, collocated and distributed space-time block codes (DSTBCs) which admit multigroup maximum-likelihood (ML) decoding are studied. First, the collocated case is considered and the problem of constructing space-time block codes (STBCs) which ...
Performance analysis of a multihop relay network using distributed Alamouti code
In this paper, we apply the classical Alamouti coding technique in a distributed and cascaded fashion to multihop relay networks where relays perform the decode-and-forward (DF) protocol at each relay stage. The considered system consists of two ...
