Turbo packet combining techniques for multi-relay-assisted systems over multi-antenna broadband channels

This paper focuses on turbo packet combining techniques for multi-relay-assisted systems operating over multiple-input multiple-output (MIMO) broadband channel. Two packet combining techniques are studied, signal-level packet combining and soft information-based combining. In this paper, a comparative study, in term of implementation cost and performance evaluation, is presented. Using complexity analysis and throughput simulations, we demonstrate that the choice of the best combining technique depends on the system configuration. Categories and Subject Descriptors C.2.1 [Network Architecture and Design]: Wireless communication. General Terms Algorithms, Performance. Keywords Cooperative relaying, multiple-antenna systems, turbo equalization, packet combining.
