Performance study of cdma2000 system ' s reverse channels 2000系統反向信道的性能研究
It consists of a powr compensation algorithm based on reverse channel prediction and closed - loop power control algorithm . computer simulation showed that the scheme could compensate the fast channel fading quite well 它由基于反向信道預測的功率補償算法和常規閉環功率控制組合而成。計算機仿真結果表明,所提出的組合功率控制方案能夠很好地補償信道的快速衰落。
The approach in this thesis first design the best performance channel code in different channels and different snr , then design the adaptive coder / decoder . the receiver continually estimates the fading and noise of the channel and transmits them to the transmitter by reverse channel . then the transmitter use these information to choose the best channel code adaptive the current channel 本文提出的自適應調制方案首先設計各種信道衰落和信噪比條件下的最優信道編碼,再設計一種能夠完成這些信道編碼解碼的自適應編碼解碼器;接收機不斷估計信道的衰落程度和噪聲功率,并通過反向信道反饋給發射機;發射機據此選用最適合當前信道的信道編碼,實現自適應。
