In the code division multiple access ( cdma ) system, the multiple access interference ( mai ) mitigation capability as well as system capacity are determined, to a great extent, by the correlation properties of spreading sequences ; while adaptive modulation and coding ( amc ) with high spectral efficiency is the key technique to obtain high speed and low symbol error rate ( ser ) performance in mobile data transmission
在碼分多址( cdma )系統中,擴頻序列的特性在很大程度上決定了抗多址干擾( mai )能力和系統容量,而高頻譜效率的自適應調制編碼( amc )技術則是獲得高速率和低誤碼率( ser )移動數據傳輸性能的關鍵因素。
