The purpose of this paper is to improve the detection sensitivity of radio interferometry. The development of wideband signal processing techniques is necessary for high-sensitivity radio interferometry. The higher-order sampling technique can achieve wider bandwidth than expensive wide-baseband conversion system. The over sampling technique can improve the quantization loss from 11.89% to 3.99% at the 4-level quantized sampling. Moreover, the digital filter can reduce the folding noise incurred by the non-rectangular frequency response at a sampling process. It is confirmed that the wideband and low-loss A/D conversion system may be realized by implementing the higher-order sampling, over sampling and digital filtering techniques. In this paper, the key features focusing on these advanced techniques for radio astronomy are presented in detail.
