The invention belongs to the technical field of radio and particularly relates to a broadband large dynamic four-channel digital receiver. The broadband large dynamic four-channel digital receiver comprises four groups of intermediate frequency signal receiving units, a clock distributor, a programmable down converter, an FPGA control chip, an EPROM and a driver, wherein the four groups of intermediate frequency signal receiving units are completely the same in structure and are independent on one another. One to four paths of I / Q data signals can be output according to actual requirements, four independent broadband channels are integrated into one line, and the functions of the four-channel digital receiver can be achieved on one integrated chip, so that resources are greatly saved; the hardware cost is reduced; the circuit is simple in structure, high in integration level, low in cost and small in volume; the circuit design is simplified by selecting universal components.
Description
technical field [0001] The invention belongs to the field of radio technology, in particular to a wide-band and large-dynamic four-channel digital receiver. Background technique [0002] Since the concept of software radio was proposed in 1992, it has been developed for 25 years. Its core is to use open, scalable, and simplified hardware as a general platform, and use as many radio functions as possible with reconfigurable and upgradeable Componentized software to achieve. Digital receiver is one of the core technologies of software radio, and it can use a common platform with component software to realize multi-field applications. [0003] The digital receivers in the prior art usually have complicated circuit structure, high hardware cost and large volume. Therefore, it is urgent to propose a digital receiver with simple circuit structure, high integration, low cost and small volume. Contents of the invention [0004] In order to overcome the above-mentioned deficienci...
