Abstract

The invention discloses a digital receiver module, a signal processing method thereof, and a radio frequency card wiring method. The digital receiver module comprises a signal collection unit, a clock management unit, a synchronous speed reduction processing unit, and a signal processing unit. The clock management unit supplies a superspeed sampling clock for the signal collection unit, and provides a synchronous speed reduction processing clock for the synchronous speed reduction processing unit, wherein the synchronous speed reduction processing clock is coherent with the sampling clock. The signal collection unit achieves the sampling and single-bit quantification of a radio-frequency input signal, and outputs superspeed single-bit collection data. The synchronous speed reduction processing unit enables one-path superspeed serial data to be converted into 16-path high-speed parallel data through first level speed reduction processing. The signal processing unit provides an on-line adjustable time delay code value in the synchronous speed reduction processing unit, and completes the real-time processing of high-speed parallel data. The invention also discloses the signal processing module for the digital receiver module, and the radio frequency card wiring method for the digital receiver module.
