In this dissertation we present new methods for designing efficient Raptor codes in finite and practical block lengths. First we propose an extension of Raptor codes which keeps all the desirable properties, including the linear complexity of encoding and decoding per information bit, and...

In opportunistic relaying systems, only the relay with best channel condition among K relays is selected to take part in cooperation. This setup efficiently achieves diversity gain. However, the high switching rate of such systems may be undesirable due to practical implementation issues, for...

Performance evaluation and protocol design of fixed-rate and rateless coded relaying networks
DownloadSpring 2011
The importance of cooperative relaying communication in substituting for, or complementing, multiantenna systems is described, and a brief literature review is presented. Amplify-and-forward (AF) and decode-and-forward (DF) relaying are investigated and compared for a dual-hop relay channel. The...
