OFDMA系统中的静态功率分配算法研究
Research on the static power allocation algorithm of OFDMA system
【摘要】 对正交频分复用多址(OFDMA)系统中的功率分配算法进行了研究,着重研究了等功率分配、以跟踪大尺度衰落(TLSF)和跟踪大尺度干扰(TLSI)为目标的三种纯静态功率分配算法。并通过系统级仿真考察了它们对OFDMA系统性能的影响。
【Abstract】 The power allocation algorithm in OFDMA system has been studied in this paper. We present three kinds of pure static power allocation algorithms, EP (equal power allocation), TLSF (whose target is to track large-scale fading) and TLSI (whose target is to track large-scale interference). And their performances have been evaluated through several system level simulations. The simulation results show that: The system performance with TLSI is 10.3% higher than with TLSF, and 19.4% higher than with EP.
