Digital transceiver, system, control method, device and storage medium thereof

Abstract

The invention discloses a digital transceiver, a system, a control method, a device and a storage medium thereof. At least two filtering channels are disposed in a digital frequency conversion module,each filtering channel is provided with an independent mixing unit and filtering unit, thus signals are enabled to realize multi-channel parallel transmission, and transmission efficiency is improved; at the same time, the mixing unit and the filtering unit of each filtering channel are independent, thus frequency points among all the filtering channels are relatively independent, and thus different frequency points can be processed; and in addition, the filtering unit is arranged as a cascade combination of a plurality of filters, thus different transmission rates can be realized, and internal logic resources of an FPGA (Field Programmable Gate Array) device are 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 Dr. JosephMitolaIII in May 1992 . 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 (Look-Up-Table ) l...

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.
