Abstract
In cdma2000 1xEV-DO Broadcast and Multicast Services (BCMCS), Reed-Solomon coding is applied to the layers above the turbo code, and is particularly effective in correcting long bursts of errors. An additional block interleaving mechanism improves the performance of RS coding by increasing the time diversity, to an extent controlled by the width of the error control block (ECB), which converts error bursts into random patterns. We propose and evaluate a performance model of RS coding under varying conditions of Rayleigh fading on the broadcast channel, within the levels of block interleaving that the BCMCS specification allows. Simulation results show that our model predicts the performance of RS coding accurately. This evaluation will allow a service provider to determine the most efficient RS code for their target service quality, that maximizes the effective data-rate and minimizes the energy required for the RS decoding process.
