Reducing End-to-End Distortion in Noisy Wireless Relay Networks

This paper investigates the provisioning of multimedia services from a novel perspective of reducing End-to-End Distortion (EED) in a decode-and-forward relay network. Exploiting a logical mapping between scalable source information and SuperPosition Coding (SPC), a benchmark for EED evaluation is formulated and applied to demonstrate achievable gains of the SVC-SPC architecture in a fundamental three-node relay network. Performance impact under various fading channel conditions is investigated via numerical experiments when Successive Interference Cancellation (SIC) is employed for SPC signal decoding.
