隱匿性間隔旁道的診斷及射頻消融方法學探討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播的需求條件,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間隔技術等核心技術,使之能抵抗高電平( 0db ) ,長延時的靜態和動態多徑失真,有利於數字和模擬電視的混合傳輸,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。Based on piecewise linear model, this paper proposes an estimation method that first estimates the slope of linear variant and the channel impulse response at the middle time of the current ofdm symbol using pilot sequences, and then estimates the whole channel impulse response through the estimated parameters
該演算法首先利用導頻序列估計出當前ofdm符號間隔內通道線性變化的斜率和中間時刻通道的沖激響應值,然後根據線性模型利用估計出的參數得到當前符號間隔內所有時刻上的通道沖激響應。The millimeter wave diplexers used in the ka - band satellite communications are investigated. these diplexers are of high working frequency, narrow passband and high selectivity, which demands the channel filters good performance
所研究的毫米波雙工器工作頻率高(接近40ghz ) ,收發通道帶寬窄、接收頻率和發射頻率間隔很小。All guest rooms are equipped with advanced locking systems, an integrated power supply, sound proof doors and a personal security alert button in the bathroom. individual controls for the heating and cooling system, international satellite television channels, idd telephone system with bathroom extension, hair dryer, large bath, shower cubicle, mini bar, electric kettle, complimentary tea and coffee, electronic safe, large desk and high speed internet access are standard
