In this paper, the authors quantitatively analyze the gain in error-constrained bit throughput achieved by the rapid symbol duration adaptation. They focus on the adaptive system that can choose for each symbol a symbol duration only from a discrete set of symbol durations. The results show that the rapid adaptation with a discrete duration set can often achieve a throughput gain similar to that achieved with a continuous set of durations. The results are especially applicable to spreading gain adaptation in CDMA systems.
