Performance Analysis of a Multi-Hop Communication System With Decode-and-Forward Relaying
This paper analyzes the performance of a multi-hop wireless communication system, consisting of a source node, N intermediate nodes or relays, and a destination node in a Rayleigh fading environment with decode-and-forward relaying at each intermediate node. The data is therefore transmitted from source to destination through N + 1 hops. Two types of modulation, namely, M-ary Phase-Shift Keying (MPSK) and Orthogonal M-ary Frequency-Shift Keying (OMFSK), are considered for the transmitted data. In case of MPSK, each relay performs coherent detection, while in case of OMFSK, each relay performs non-coherent detection.
