Efficient offline coverage and load evaluation for CDMA network modeling

This paper addresses offline modeling for coverage and load evaluation in code-division multiple-access (CDMA) networks, where demand may exceed capacity. We introduce the offline problem of allocating transmission power to spatial snapshots of users, given their priority for admission to a network. Such network evaluation allows us to assess whether a current or potential network configuration can provide adequate physical-layer resources for a specific snapshot of users at a particular point in time. This may be reapplied many times with different snapshots of the user location and different requests for services. We introduce a new heuristic approach that substantially reduces computational complexity for the problem. We benchmark the algorithms by comparison with the simulation of online power control

Optimized network dimensioning and planning for WiMAX technology

In order to meet demands in mobile broadband and to bridge the digital divide a new technology, namely WiMAX, was introduced in 2004. However, in order to increase the financial return on the investment inWiMAX, service operators need to make every effort in designing and deploying the most cost-effective networks. This thesis presents a novel dimensioning technique for WiMAX technology which takes the dimensioning problem to a new level and produces more accurate results in comparison to the traditional methods. Furthermore, a novel decomposed optimization framework for the WiMAX network planning is introduced which subdivides the overall problem into three distinct stages consisting of the network dimensioning stage which besides the primary task of evaluating the financial requirements produces a good starting network solution for the subsequent stages (Stage 1), initial sectorization and configuration of the network (Stage 2) and final network configuration (Stage 3). The proposed framework also solves two fundamental problems, which are cell planning and frequency planning, simultaneously. The feasibility of the final network solutions are then evaluated by OPNET simulator.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
