Uniform undersampling technique of bandpass signal and its engineering application in software digital if receiver
帶通欠采樣技術及在數字中頻軟體接收機中的工程應用 -
As a result, digital images usually suffer from aliasing due to undersampling, loss of high - frequency detail due to relative motion or out - of - focus. supperresolution involves up - conversion of the input sampling lattice as well as reducing or eliminating aliasing and bluring
因此，通常數字圖像因欠采樣（ undersampling ）而引起的信號混疊，因低解析度傳感點擴散（ psf ： pointspreadfunction ）而造成的高頻部分、丟失，以及因相對運動或散焦造成的光學模糊等因素而受損。 -
The advantage and disadvantage of the method of azimuth pre - filtering and undersampling and the method of subaperture processing are compared
比較了方位向預濾波降采樣方法與子孔徑處理方法各自的優缺點。 -
The effects of sampling clock jitter on signal - to - noise ratio ( snr ) and effective bit ( enob ) performance discussed in section 3 are even more dramatic in undersampling applications because of the higher input signal frequencies
在第三章討論的采樣時鐘抖動對信噪比和有效位性能的影響在欠采樣應用中因為更高的輸入信號頻率顯得更有戲劇性。 -
At the same time the case of coherent signal sources is also discussed and an algorithm for estimating 1 - d angle - of - arrival from under - sampled data is proposed in the thesis. moreover, a system of digital signal processing receiver using spatio - temporal undersampling technique is described and some practical problems are also discussed
