Abstract BCMCS (Broadcast and Multicast Services) are designed to provide media broadcast in cellular networks. In designing media broadcast protocols and systems, such as BCMCS, delay must be thoroughly considered because it is the key QoS parameter in multimedia applications. This paper investigate the forward error correction (FEC) delay using Reed-Solomon (RS) code related to the temporal behavior of Rayleigh fading. We implemented the evaluation framework for the RS decoding delay employing analytic and simulation-based approaches. An analytic method and a simulation approach are combined in a unified environment exploiting Java programming language, ARM9 processor simulator and Mathematica coupled together. This framework enables us to estimate various statistics required to ensure seamless multimedia services.
