With the progress of digital signal processing technique, pulse compression processing system are developed from analogue or digital - analogue system to all digital ones. digital pulse compression processing can be divided into pulse compression processing in time domain and pulse compression processing in frequency domain
隨著數字信號處理技術的進步,脈壓處理系統也從模擬式、數模結合式發展到全數字式,數字式脈壓處理又分為時域脈壓處理和頻域脈壓處理。 -
This thesis presents the time domain character and frequency domain character of common used signals, including digital modulation signals and analogue modulation signals. the first method is to extract feature parameters from time domain and frequency domain. it can distinguish 2ask, 4ask, 2fsk, 4fsk, bpsk, qpsk, 16qam, 64qam and it is demonstrated by simulation data and sampled data
本文介紹了常用的通信信號(包括模擬調制樣式和數字調制樣式)的時域、頻域特徵,首先從時頻域提取信號的特徵參數,用於區分2ask 、 4ask 、 2fsk 、 4fsk 、 bpsk 、 qpsk 、 16qam 、 64qam這8種信號,用模擬信號和實際采樣信號驗證了該方法的可行性。 -
This process, including analogue video conversion from difference signal to single signal and digital video processing which is the real time transformation of electronic canceling image - rotation is realized by designing a video - signal - board
