cyclic prefix

基本解釋

A symbol timing algorithm for orthogonal frequency division multiplexing(OFDM) systems with the cyclic prefix under wireless channels is proposed.
提出了一種新的無線信道下基于循環(huán)前綴的正交頻分復(fù)用系統(tǒng)符號定時(shí)同步算法。
If the length of its cyclic prefix is larger than the delay spread of transmission channel, we can get a simple frequency equalizer to demodulate OFDM signal.
對于傳統(tǒng)的OFDM系統(tǒng)來說，如果循環(huán)前綴的長度大于信道的時(shí)延擴(kuò)散值，則可以通過簡單的頻域均衡來解調(diào)OFDM信號。
Tail cancellation and cyclic reconstruction are applied in SFBC-OFDM system to eliminate the bandwidth loss of space-frequency coding due to the cyclic prefix.
將尾抵消和循環(huán)重建應(yīng)用于空頻編碼的正交頻分復(fù)用（SFBC-OFDM）系統(tǒng)中，為了消除循環(huán)前綴對空頻編碼帶寬損失的影響，使用了迭代算法來校正接收到的信號。
