  1. Verification regulation of tv colour subcarrier frequency comparator

    彩色電視副載頻校頻儀檢定規程
  2. 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。
  3. A pilot subcarrier - based joint frequency offset correction and channel estimation method for ofdm systems

    系統中一種基於導頻子載波的聯合頻率偏移糾正和通道估計方法
  4. A joint frequency and space diversity scheme is presented which can reduce computational cost. 3. an adaptive bit, power and subcarrier allocation is presented

    分集技術,重點介紹了一種空間頻率聯合分集接收技術,它能夠大幅度降低計算量; 3
  5. It combines the advantages of ofdm and cdma. it can convert the frequency selective channel propagation of the broadband to flat channel of the subcarrier

    它結合了ofdm和cdma技術的優點,能夠把寬帶頻率選擇性衰落轉化為每子載波的平坦通道。
