According to the amount and complexity of computation for cross-layer resource allocation algorithm,an adaptive cross-layer resource allocation scheme employing Genetic algorithm(GA) in multiuser OFDMA system is proposed.A better solution to the cross-layer resource allocation satisfying system performances and users' requirements is presented based on the GA characteristics such as parallel processing,comprehensive ability of global search and easy convergence to the optimum.Under the prerequisite of fairn...
引言正交频分多址接入(orthogonal frequency divisionmultiple access,OFDMA)是利用OFDM将信道划分为多个载波后,在部分子载波上加载传输数据的一种新的传输技术。每个用户可以选择信道条件较好的子信道进行数据传输,保证各子载波被信道条件较好的用户使用。OFDMA系统利用子载
