直接串音 的英文怎麼說
中文拼音 [zhíjiēchuànyīn]
直接串音
英文
direct crosstalk-
In other way, the telephone line expander which has many characteristics just as the little of declination, the far distance of communication, the convenience of using and protecting can transmit tone signal directly and is suitable for the performance of telephone line
同時，電話線路擴容器直接傳輸音頻信號，適合電話線路特性，具備衰耗及串音小，通話質量好和通信距離遠，使用及維護簡便等優點，具有廣泛的應用前景和使用價值。Transmition velocity relys on the style of encode and modulation essentially during modern data transmition for the quality of using line bandwidth and the immunity of code ties on them tightly. but it is important that the velocity of data transmition reaches its limitation in fact for the interface of environment and cross - talk. so for the improvement of transmition velocity, we must analyze the characteristics of noise signal and the model of line deeply and then take some useful measures to better the immunity of modulation wave
在現代通信的數據傳輸過程中，傳輸速率本質上是由傳輸的編碼方式和調制方式決定的，因為編碼方式和調制方式直接決定了線路頻帶利用率和碼元抗干擾能力的好壞，因而直接決定了傳輸速率；但是在實際應用過程中，數據傳輸速率是不可能達到理想狀況的，因為環境干擾、串音干擾等因素的存在使得線路的頻帶不可能被完全利用起來；因此，必須認真分析線路的噪聲信號的特性以及噪聲線路的模型，以便在編碼方式和調制方式中針對性的做一些改進措施以改善調制波形的抗干擾能力，使得傳輸速率能夠進一步提高。The current studies on query by humming focus on humming in special way and approximate string matching. little attentions are put on humming in continuous way, and even using the continuous input method, the matching is still based on the sequence of pitches which has not been processed first
目前對哼唱音樂檢索的研究大多把重點放在特定哼唱輸入方式和字元串之間的模糊匹配上，對于連續哼唱輸入方式的研究較少，即使採用了連續哼唱輸入方式，也是直接提取哼唱輸入的基頻軌跡進行匹配，缺少對基頻軌跡預處理的研究。
