Wireless communication full-digital radio frequency receiving device

Abstract

The invention relates to a wireless communication full-digital radio frequency receiving device. The wireless communication full-digital radio frequency receiving device comprises a radio frequency pulse width modulation analog-to-digital conversion module and a multi-phase digital down-conversion module, the radio frequency pulse width modulation analog-to-digital conversion module samples and quantizes received radio frequency analog signals through pulse width modulation to obtain analog input digital signals; and the multiphase digital down-conversion module is used for multiphase decomposition of the digital signal and the oscillation signal into a plurality of sub-channels for parallel low-speed sampling, carrying out down-conversion operation on each channel of input data, and usingparallel down-conversion of the plurality of sub-channels to achieve down-conversion of the input digital signal. High analog input bandwidth and flexibility can be provided, equivalent down-conversion of high-speed sampling signals is achieved, the structure of a receiver is simplified, and cost and power consumption are reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an all-digital radio frequency receiving device for wireless communication. Background technique [0002] With the continuous growth of user capacity and the rapid development of new technologies and applications, the data rate of mobile communication systems is increasing at an unprecedented rate. In addition to high data rates, 5G networks require next-generation wireless base stations to cope with interoperability between different technologies and heterogeneous networks, denser base station deployments, higher power efficiency, and more communication between IoT-enabled devices. connect. Therefore, it is particularly important to find a digital receiver with small size, low power consumption, high bandwidth, high flexibility and strong scalability to promote the development of 5G. [0003] Traditional RF receivers are usually based on a homodyne or heterodyne...

Problems solved by technology

Applied to radio frequency signals, the cost is high, and there is no exact method to obtain the best reference waveform to optimize the performance of the receiver. If the reference waveform parameters are not set correctly, the generated pulse width modulation signal will contain out-of-band harmonic components. can fold in samples and interfere with the spectrum of the desired signal
