A digital transceiver, system, control method, device and storage medium thereof

Abstract

The invention discloses a digital transceiver, system, control method, device and storage medium thereof. By setting at least two filter channels in the digital frequency conversion module, and each filter channel is provided with an independent frequency mixing unit and filter unit, The signal can be transmitted in parallel with multiple channels, which improves the transmission efficiency. At the same time, since the frequency mixing unit and the filtering unit of each filter channel are independent, the frequency points between the filter channels are relatively independent, so different channels can be processed. In addition, by setting the filter unit as a cascaded combination of multiple filters, different transmission rates can be achieved, and the internal logic resources of the FPGA device can be effectively saved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a digital transceiver, system, control method, device and storage medium thereof. Background technique [0002] Software-Defined Radio (SDR) is a new type of radio architecture, which enables wireless networks and user terminals to have reconfigurable capabilities through the combination of hardware and software. This concept was first proposed by Joseph Mitola in May 1992. presented by Dr. III. The digital transceiver includes the up / down conversion of digital signals, which is the core technology of software radio transmission and reception, and is also an important part of the satellite communication system. [0003] FPGA (Field Programmable Gate Array) is a field programmable gate array, which is a kind of programmable logic device. After decades of development, it has become one of the mainstream platforms for realizing digital systems. It is based on LUT (Loo...

Problems solved by technology

Generally speaking, the signal rate of AD sampling output is relatively high. Due to the limitation of the current hardware level, the existing DSP platform cannot directly process it, so it is gradually developed to use FPGA for processing.

However, the existing FPGA-based digital transceiver devices usually deal with a single frequency point, which cannot realize the independence of multiple frequency points and rates between multiple channels, and consumes a lot of resources.
