  1. And pays emphasis on analyzing the system structure and system flow, the core techniques, the channel characteristic and parameters of dvb - t system. the system adopts some core techniques such as cofdm, a lot of tps ( transmission parameter signalling ) insert and guard interval, and so on. so it can withstand high - level ( up to odb ), long delay static and dynamic multipath distortion

    論文首先描述了數字電視地面廣的需求條件,技術難點和目前存在的問題,並重點分析了dvb - t系統結構流程,核心技術及系統通道特性和參數,該系統採用了cofdm (編碼正交頻分多路復用) ,大量導頻信號插入和保護技術等核心技術,使之能抵抗高電平( 0db ) ,長延的靜態和動態多徑失真,有利於數字和模擬電視的混合輸,它的多載波調制模式功能和性能在移動和便攜接收、同頻網等方面具有獨特的優勢。
  2. Travel time is the key point of system, its measure quality decides the survey precision of the stress. time to digital convertor ( tdc ) was applied to accomplish the precision time interval measurement. at the same time, one transmitter - two receivers probe arrangement and zero - crossing detecting method were also applied to reduce the errors in measurement

    是整個測量系統中的關鍵量,其測量水平決定應力的測量精度,對此本文採用-數字轉換器( timetodigitalconvertor , tdc )完成高精度測量,在實現過程中又分別採用「單端發射-雙端接收」的探頭布局模式和「過零檢測」手段來降低系統檢測誤差。
