Variable Bit Allocation for FH-CDMA Wireless Communication Systems
Overview In the wireless indoor environment, the channel may vary slowly as users and the interferers may move at slow speeds. A frequency-hopped code-division multiple-access system can adapt to the different interference levels in hopping patterns and assign the slots different bit rates to increase the system capacity. This paper shows that the maximum throughput bit-rate/channel-assignment problem is NP-hard. Several practical ad hoc bit allocation algorithms are designed based on the insights derived from exhaustive searches. The algorithms that achieve the most system capacity perform interference avoidance.
