Adaptive cell sectorization for CDMA systems
Given the user distribution in a cell, we investigate the two problems of how to appropriately sectorize the cell such that we minimize the total received power and the total transmit power of all the users, while giving each user acceptable quality of service in both cases. For the received power optimization problem, we show that the optimum arrangement equalizes the number of users in each s...
متن کاملCapacity enhancement for CDMA systems through adaptive cell sectorization
We consider the problem of adaptive cell sectorization i n a CDMA system. Specifically, given the user distribution in a cell, we investigate the two problems of how to appropriately sectorize the cell such that we minimize the total received power and the total transmit power spent by all the users, in both cases, while giving each user acceptable quality of service. The optimum arrangement eq...
متن کاملAdaptive CDMA Cell Sectorization with Linear Multiuser Detection
We consider the problem of adaptive cell sectorization in a CDMA system when the receiver employs a linear multiuser detector. Specifically, given the number of sectors and terminal locations, we investigate how to appropriately sectorize the cell, such that the total transmit power is minimized, while each user has acceptable quality of service, under the assumption that the base station emplo...

AbsfracfWe consider the adaptive sectorization problem for a CDMA system under the imperfect directional antenna. Specifically, given the number of sectors and terminal locations, and assuming base station employs linear multiuser detection, we investigate how to appropriately sectorize the cell, such that the total transmit pon'er is minimized, while each user has acceptable quality of service...
متن کاملAn efficient algorithm for adaptive cell sectoring in CDMA systems
Cell Sectorization is a promising method for improving the capacity of code division multiple access (CDMA) systems. It has been shown that the use of adaptive antenna arrays with dynamic cell sectoring is particularly suitable for non-uniformly distributed users. In this paper, we present a novel Cluster-based Sectoring algorithm for adaptive cell sectorization. The complexity of our algorithm...
