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.
由于接收端是不同用戶(hù)信號(hào)的疊加,使得OFDMA系統(tǒng)的頻偏補(bǔ)償變得異常的困難。
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(lái)越多的應(yīng)用。
Carrier Frequency offsets in OFDMA system will introduce InterCarrier Interference (ICI) and consequently degrade the system performance.
由于載波頻偏會(huì)給正交頻分多址接入OFDMA系統(tǒng)帶來(lái)子載波之間干擾，從而造成多用戶(hù)之間的干擾，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(duì)同步誤差敏感的缺點(diǎn)，尤其是對(duì)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.
提出了一種用于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)。
