An ultra-wide frequency receiving method of pulse peak detection wave and its receiver

Abstract

The invention discloses a super bandwidth receiving method and receiver of a pulse peak detection, which is characterized by the following: making the peak envelope dose received the signal by the antenna and extracted by the detector into the digital signal by the comparator; sampling the quantized envelope signal according to the code element cycle per path by the parallel multi path sampling circuit; coding according to the sequence of the sampling from small to big; dealing with every path and the frame sequence; determining that the sampling time of the smallest path is the origin of pulsed signal in the corresponding output more than threshold and the digital is the origin of the frame signal; inputting the parallel multi path signal and sliding a code element cycle and proceeding with the above process again if not; adding the sampling value when the original time and a plurality of the subsequent numbers aren't less than one and more than the sampling path number; judging ' 1' if more than the set demodulation threshold; judging ' 0' if less than threshold. The invention makes the super bandwidth technique into the simple structure and the high speed communication method in the short distance wireless communication.

Description

Technical field: [0001] The invention belongs to the technical field of pulse ultra-wideband communication, in particular to an ultra-wideband receiving method of pulse peak detection and a receiver thereof. Background technique: [0002] "Microwave Theory and Technology" (IEEE Transaction on Microwave Theory and Technology, Vol.52, Issue 9, Sep.2004, p 2087-2104) introduced the progress of pulse ultra-wideband technology, due to the nanosecond and subnanosecond width The detection of pulse signals has difficulties in reception, analog-to-digital conversion, and synchronization. The maximum rate of the existing pulse UWB communication system is only 25Mbps. [0003] At present, in the physical layer implementation scheme for ultra-wideband communication, there are usually two methods for receiving nanosecond and sub-nanosecond width pulse signals: coherent method and non-coherent method. Chinese patent CN1561006 discloses a correlation receiver and its receiving method. The...
