WiMAX系统的载波聚合技术
摘要
Abstract
Spectrum efficiency can be significantly improved by using orthogonal frequency division multiplexing technology in WiMAX system. In order to support a higher data rate, transmission bandwidth needs to be extended. Multiple component carriers are connected together by adopting carrier aggregation technology, which can provide wider transmission bandwidth. In this paper, on the basis of testing result on spectrum utilization, continuous carrier aggregation method is used to broaden the transmission bandwidth in 230 MHz WiMAX system. Compared with discrete carrier aggregation method, continuous carrier aggregation method has a lower systematic complexity, which is convenient for application.关键词
