  1. The columns and rows are constrained by each other. the simulations over binary symmetric channe ( lbsc ) and gilbert - elliott channel ( gec ) shows the performance is great improved, especially over burst error channel peak signal to noise ratio ( psnr ) is improved more. it is tried to be used in wireless communication system

    模擬結果表明，採用行列交替約束的約束維特比譯碼以後，性能得到較大的提升，尤其在突發錯誤通道中，傳輸的圖像經乘積編碼進行通道編碼與譯碼后峰值信噪比有明顯的提高。
  2. Measurements include frequency, frequency ratio with optional channel 2, period and peak voltage

    量測包括頻率頻率比使用第2個頻道選項周期與峰值電壓。
  3. Frequency - domain equalization. at the same time discusses some key problems in ofdm : high ratio of peak - to - average power of output signals, problem of synchronization, channel estimation, adaptive bit, power and subcarrier allocation. emphasize on channel estimation, and present a new algorithm which can filtering more interpolation errors and noise. for the sake of improve the performance of resist narrowband noise and make efficient use of the spectrum apply malvar wavelet division

    同時就ofdm系統中的一些關鍵問題如峰值平均功率比（ papr ）太高，同步問題，通道估計，通道、比特與功率必須動態分配進行了研究，著重研究了通道估計問題並提出一種改進的方法，能濾除更多的噪聲分量和插值誤差，提高系統的性能；為了提高抗窄帶噪聲的性能和提高通道利用率，用malvar小波變換實現了不等帶寬分配。
  4. At the same time, a simple channel estimator that can suppress the peak - to - average power ratio ( papr ) for ofdm system with multiple transmitter antennas is proposed, its simulation proves again the result. ( 5 ) ofdm receiver is proposed with multiple transmitter antenna and alamouti scheme

    結果表明，多個獨立天線ofdm系統的性能明顯優于單天線的ofdm系統；同時還給出了一種簡單的能有效抑制峰值功率平均功率比（ papr ）且適于多發射天線ofdm系統的導頻符號輔助的通道估計方法，模擬結果再次證明了上述結論。
  5. Peak - ratio channel

    峰比率通道
