A wireless communication all-digital radio frequency receiving device

Abstract

The invention relates to an all-digital radio frequency receiving device for wireless communication, which includes a radio frequency pulse width modulation analog-to-digital conversion module and a multi-phase digital down-conversion module, and the radio frequency pulse width modulation analog-to-digital conversion module passes the received radio frequency analog signal The modulation realizes the sampling and quantization of the analog signal to obtain the digital signal of the analog input; the multi-phase digital down-conversion module multi-phase decomposes the digital signal and the oscillation signal into multiple sub-channels of parallel low-speed sampling, and each of the input data The channel performs a down-conversion operation, and the down-conversion of the input digital signal is realized by parallel down-conversion of multiple sub-channels. The invention can provide high analog input bandwidth and flexibility, realize equivalent down-conversion of high-speed sampling signals, simplify receiver structure, and reduce cost and power consumption.

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
