OFDMA

基本解釋

Since the received signal is the superposition of multi-user"s, it makes much difficult of CFO for the OFDMA system.
由於接收耑是不同用戶信號的曡加,使得OFDMA系統(tǒng)的頻偏補償變得異常的睏難。
Orthogonal Frequency Division Multiple Access (OFDMA) gains an increasing attention for broadband wireless access (BWA) system.
OFDMA在BWA系統(tǒng)中得到越來越多的應(yīng)用。
Carrier Frequency offsets in OFDMA system will introduce InterCarrier Interference (ICI) and consequently degrade the system performance.
由於載波頻偏會給正交頻分多址接入OFDMA系統(tǒng)帶來子載波之間乾擾，從而造成多用戶之間的乾擾，導(dǎo)致系統(tǒng)性能下降。
OFDMA inherits from OFDM the weakness of being sensitive to synchronization errors, especially to carrier frequency offset(CFO).
OFDMA系統(tǒng)繼承了OFDM對同步誤差敏感的缺點，尤其是對載波頻率偏移(CFO)。
A multicell adaptive resource allocation(MARA) scheme was proposed for downlink orthogonal frequency division multiple access(OFDMA) cellular system.
提出了一種用於正交頻分多址通信系統(tǒng)下行鏈路的多小區(qū)自適應(yīng)資源分配算法(MARA)。
