摘要:
測井電纜作為測井數據傳輸系統的物理媒介,其較長的沖激響應特性使傳輸信號產生嚴重的畸變,使接收端信號產生嚴重的拖尾和碼間干擾,導致通信系統性能惡化。在基于正交頻分復用技術的測井電纜通信系統中,縮短這種信號拖尾的有效方法是時域均衡技術,利用時域均衡器縮短電纜信道沖激響應,使均衡后的信號拖尾長度小于正交頻分復用碼元的循環前綴長度,從而消除碼間干擾。提出一種低復雜度的時域均衡器設計方法,能夠快速實現時域均衡器設計中的信道估計和時延優化算法。在7 000 m測井電纜條件下測試結果表明,該方法設計的時域均衡器能夠有效改善測井電纜傳輸系統在循環前綴長度不足時的系統性能
Abstract:
Logging cable is the physical medium that is used in logging data transmission system. Its inherent character of long impulse responses causes serious distortion of the transmission signal, serious tailing and intersymbol interference of the receiver signal, and worsen the performance of the communication system. In the well logging cable communication system based on orthogonal frequency division multiplexing(OFDM)technology, an effective way to shorten the signal trail is time-domain equalization technology. The time-domain equalizer is used to shorten the impulse response of the cable channel, so that the trail length of the balanced signal is less than the cyclic prefix length of orthogonal frequency division multiplexing symbols, so as to eliminate the intersymbol interference. This study presents a low complexity design method of the time-domain equalizer which achieves algorithm of channel estimation and time delay optimization rapidly. The test results under the condition of 7 000 m logging cable show that the time-domain equalizer designed by this method can effectively improve the performance of logging cable transmission system when the length of cyclic prefix is insufficient
