OFDMA

常見例句

• 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(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)自適應資源分配算法(MARA)。
• Hence, a frequency reuse scheme which improves CEU performance by inter-cell interference mitigation is proposed for OFDMA systems here.
  爲此，該文提出了一種OFDMA系統(tǒng)中的頻率複用方法，通過抑制小區(qū)間乾擾提高小區(qū)邊緣用戶性能；
