OFDMA
基本例句
正交频分多址¹⁰⁰
Since the received signal is the superposition of multi-user s, it makes much difficult of CFO for theOFDMAsystem.由于接收端是不同用户信号的叠加,使得OFDMA系统的频偏补偿变得异常的困难。
Orthogonal Frequency Division Multiple Access gains an increasing attention for broadband wireless access system.OFDMA在BWA系统中得到越来越多的应用。
Carrier Frequency offsets inOFDMAsystem will introduce InterCarrier Interference and consequently degrade the system performance.由于载波频偏会给正交频分多址接入OFDMA系统带来子载波之间干扰，从而造成多用户之间的干扰，导致系统性能下降。
OFDMAinherits from OFDM the weakness of being sensitive to synchronization errors, especially to carrier frequency offset.OFDMA系统继承了OFDM对同步误差敏感的缺点，尤其是对载波频率偏移。
A multicell adaptive resource allocation scheme was proposed for downlink orthogonal frequency division multiple access cellular system.提出了一种用于正交频分多址通信系统下行链路的多小区自适应资源分配算法。
Hence, a frequency reuse scheme which improves CEU performance by inter-cell interference mitigation is proposed forOFDMAsystems here.为此，该文提出了一种OFDMA系统中的频率复用方法，通过抑制小区间干扰提高小区边缘用户性能； |
