一种新颖的多用户OFDM资源分配算法
A novel power allocation algorithm in multiuser OFDM systems
摘要
Abstract
A novel subcarrier power allocation algorithm was to maximize the user data transmission rate in multiuser OFDM systems. The algorithm was divided into two parts: subcarrier allocation and power allocation. Subcarrier allocation allocated subcarriers which had the best channel capacity to users; and power allocation used water-filling. Studies and simulation results showed that the algorithm by only changing the gain coefficients of subcarriers substantially maintains a low complexity, greatly improves the user data transmission rate.关键词
