The Analysis Of WCDMA System's Coverage And Capacity

Because the WCDMA system is a self-jamming system, capacity, coverage, and interference are close correlation. at the same time the WCDMA is a multi-service and multi-speed rate system, the different service to system capacity taking is the dynamic allocation process, therefore the WCDMA network capacity planning will greatly complexity which to compared with the narrow band frequency planning. When the 3rd generation has not entered commercial stage, the network pre-plan is very important to the after construction investment and the network quality.This article will in view of the coverage and the capacity planning, which are most important in the network planning. analyzes important parameter, considered each kind of interference effect, obtains system coverage under each kind of different environment and the service; Then through the theoretical analysis, calculates the capacity formula and with each influence factor relations, confirms it through the simulation under the specific condition's cell capacity; Aim at the function of interference remainder value to network planning , changes when the plan with a dynamic adjust method changes the remainder the value, thus make the planning more credible; Finally, utilizes the Monte-Carlo simulation method and combines actual environment to confirm above analyze.
