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於循環(huán)前綴的正交頻分複用系統符號定時同步算法。
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.
對於傳統的OFDM系統來說，如果循環(huán)前綴的長度大於信道的時延擴散值，則可以通過簡單的頻域均衡來解調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.
