high speed and broadband Digital Receiver based on optical sampling pulse waveform matching
Optics Letters, 2020Co-Authors: Sitong Wang, Liang Hu, Jianping Chen, Guiling WuAbstract:In this Letter, we propose a high-speed, broadband photonic Digital Receiver that can realize the matched filtering of the Digital signal through shaping the optical sampling pulse according to the specific waveform of the transmitted Digital signal. The Receiver’s filtering response is matched with the spectrum of the Digital signal’s specific waveform, and the instantaneous signal-to-average-noise ratio of the filtered signal is maximized at the sampling points. The principle of proposed Receiver is theoretically analyzed and experimentally verified. The weak Digital signals with different signal-to-noise ratio are detected and correctly distinguished in the experiments.

Design of RFID Digital Receiver Based on FPGA
Computer Engineering, 2007Co-Authors: Min HaoAbstract:A novel design of RFID(radio frequency identification) Digital Receiver is presented.In order to meet the real time requirement for RFID system,this paper uses simplified correlation algorithm instead of the DPLL(Digital phase lock loop) structure.The Receiver can adaptively capture the burst mode input signal ranged from 31.2kHz to 780.8kHz and finish the decoding process.The design is more robust to noise interference compared with that using the zero crossing method.The Digital Receiver is implemented on Altera Stratix II EP2S60 and has great performance.

Finite-resolution Digital Receiver design for impulse radio ultra-wideband communication
IEEE Transactions on Wireless Communications, 2008Co-Authors: Huarui Yin, Weilin Gong, Zhengdao WangAbstract:Receiver design for impulse radio based ultrawideband (UWB) communication is a challenge. High sampling rate high resolution Digital Receiver is usually difficult to implement. Some tradeoffs can be made on the Digital Receiver, such as limiting amplitude resolution to only one bit, which results in a previously considered monobit Receiver. In this paper, we consider the design of finite-resolution Digital UWB Receivers. We derive the optimal post-quantization processing, and analyze the achievable bit-error rate performance using an approximation of the log-likelihood ratio. Optimal thresholds for 4- and 3-level quantization are obtained. Training-based Receiver template estimation is presented. Our work discloses the incremental gain that additional quantization levels offer and the results provide useful guidelines for designing impulse radio UWB Digital Receivers.
