Based on the importance of pulse / pattern generator, the work of this dissertation comes from the project “ high speed pulse / pattern generator ”, which is taken on by the university of electronic science and technology of china. the dissertation focuses on the process of pulse generating, and its main task is to generate pulse waveforms with adjustable parameters ( including period, pulse delay, pulse width and etc )
基於研發脈沖/數據發生器的重要性,結合電子科技大學承擔的科研項目「脈沖/數據發生器」 ,本文圍繞脈沖的產生的過程進行展開研究,主要任務是實現具有各種參數(包括周期、脈沖延遲、脈沖寬度等)可調的脈沖數字波形。Simulator presented in this paper provides a direct interface for the test of shortwave communication system, which well represents various features of hf channel such as multi - path delay, rayleigh fading, doppler shift, doppler spread, gaussian noise and impulsive interference, etc. in order to realize the channel simulation for the intermediate frequency signal, we, inspired by the idea of soft - defined radio, bring forward a new design method that the channel simulator consists of several dsp chips
本文研製的模擬器提供介面直接對短波通信系統進行測試,能夠全面反映短波通道的多徑時延、瑞利衰落、多普勒頻移、多普勒擴展、高斯噪聲和脈沖干擾等特性。為了實現對中頻信號的通道模擬,開發出一個結合軟體無線電思想的由多個數字信號處理晶元構成的短波通道物理模擬器。
