Space-time coding and spatial diversity schemes enhance the performance of energy constrained multihop clustered relay networks. The purpose of this thesis is to evaluate the performance of techniques such as the decode-and-forward with cooperative diversity and the Alamouti space-time coding, which were primarily used in relay multiple-input multiple-output communications, in distributed clustered two-hop and multihop relaying networks consisting of single-antenna terminals. Simulation results, in single carrier Rayleigh and Stanford University Interim channels for phase shift keyed and quadrature amplitude modulation, show that the use of the decode-and-forward with cooperative diversity and the Alamouti cooperative space-time coding schemes improve the error probability performance in a power constrained, clustered multihop relaying network operating in a multipath fading environment.
