Abstract

The invention discloses a digital reconfigurable channelized single-bit receiver and an implementation method. The receiver is composed of a 38.4 GHz sampling ultra-wideband single-bit receiver and a reconfigurable digital channelized system. The 38.4 GHz sampling ultra-wideband single-bit receiver comprises a 38.4 GHz ultra high speed single-bit ADC and an FPGA chip; the reconfigurable digital channelization system is embedded in an FPGA chip and comprises a system state machine, a rough frequency measurement module and an accurate frequency measurement module, the rough frequency measurement module and the accurate frequency measurement module multiplex a frequency measurement algorithm module, and the accurate frequency measurement module further comprises a single-bit digital frequency mixing module and a single-bit digital filtering module. Through the reconfigurable digital channelization technology, the single-bit receiver has the advantages of high frequency measurement precision, high pulse width detection precision and the like, and is easy to realize by an FPGA and high in universality.

Description

technical field [0001] The invention belongs to the technical field of single-bit receivers, and in particular relates to a digital reconfigurable channelized single-bit receiver and an implementation method. Background technique [0002] Wideband signal frequency measurement is widely used in the field of electronic reconnaissance. In order to adapt to the current complex electromagnetic environment, it is necessary to perform accurate frequency measurement in a wider frequency band. With the continuous improvement of the level of electronic devices, more and more ADCs meet the bandwidth requirements, and the sampling rate of low-bit ADCs is getting higher and higher. The emergence of high-speed sampling devices can break the complex structure that the previous frequency measurement receiver needs to convert the frequency of the signal at the radio frequency end, and then process the intermediate frequency signal at the digital end, so that the digital end of the receiver c...
