This paper evaluates the performance of recently proposed Dynamic Frequency Hopping (DFH) when applied to cellular systems with a limited total bandwidth. The paper also illustrates a practical implementation for DFH deployment using Network-Assisted Resource Allocation (NARA). The performance evaluation is accomplished by system-level simulations of a system with 12 carriers and 1/1 frequency reuse, based on the EDGE-Compact specification. Voice-only circuit-switched operation is assumed. Fading channel, multicell interference, voice activity, and antenna sectorization are modeled. The paper presents the performance of dynamic frequency hopping compared to random frequency hopping and fixed channel assignment by showing distributions of word error rates. Sensitivity to occupancy, Rayleigh fading assumptions, number of carriers, voice activity, and measurement errors are studied.
