Download E-books Performance and Implementation of Dynamic Frequency Hopping in Limited-Bandwidth Cellular Systems PDF

By Kostic Z.

We assessment the functionality of lately proposed dynamic frequency hopping (DFH) while utilized to mobile structures with a restricted overall bandwidth. We additionally illustrate a realistic implementation for DFH deployment utilizing network-assisted source allocation (NARA). The functionality overview is finished through system-level simulations of a approach with 12 providers and 1/1 frequency reuse, in keeping with the EDGE-Compact pecification. Voice-only circuit-switched operation is thought. Fading channel, multicell interference, voice job, and antenna sectorization are modeled. We current the functionality of dynamic frequency hopping in comparison to random frequency hopping and stuck channel project through displaying distributions of be aware mistakes premiums. Sensitivity to occupancy, Rayleigh fading assumptions, variety of companies, voice task, and easurement error are studied. We additionally evaluate the uplink and downlink functionality. the implications point out that DFH can considerably increase the functionality in comparison to random frequency hopping. for instance, at a 2%frame blunders cost with ninety% assurance, the capability development of DFH is nearly a hundred% compared to mounted channel task, and approximately 50% in comparison to random frequency hopping. the quantity of development for the uplink course is smaller than the development for the downlink path, in particular for better occupancies.
