OFDMA
基本解释
- 正交頻分多址
英汉例句
- 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系統中得到越來越多的應用。 - 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系統帶來子載波之間乾擾，從而造成多用戶之間的乾擾，導致系統性能下降。 - 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下行鏈路的多小區自適應資源分配算法(MARA)。
