Description

technical field [0001] The invention relates to the technical field of digital signal processing, in particular to a digital signal processing system supporting highly consistent multi-channel parallel transmission and reception. Background technique [0002] Signal reception, signal generation, signal forwarding, signal closed-loop transceiver, channel simulation and other related high-speed signal processing platforms have been widely used in communication, radar, electronic countermeasures, navigation and other fields. Due to the different application scenarios of different devices, the realization functions are different, so according to different application scenarios, multiple types of stand-alone machines are divided, and each stand-alone machine has its own hardware platform. Especially in the ground large-scale communication, radar, and electronic countermeasure systems, there are many types of stand-alone machines involved. If each functional stand-alone machine us...

Problems solved by technology

Especially in the ground large-scale communication, radar, and electronic countermeasure systems, there are many types of stand-alone machines involved. If each functional stand-alone machine uses a separate hardware platform, different hardware designs will cause inconsistencies in hardware manufacturing, testing, and maintenance. Increased the complexity and cycle of hardware equipment manufacturing

Different types of signal transceiver, signal forwarding and other equipment have inconsistent requirements for the number of signal transceiver hardware channels; different hardware will also lead to poor maintainability of application software, and too many types of components are not conducive to reducing procurement costs and increasing Design change risk due to device discontinuation

Therefore, there are several outstanding problems to be solved in the design of various equipment terminals in actual large-scale system engineering: many types of stand-alone machines, different numbers of signal sending and receiving channels, large differences in underlying drivers, long product cycles, and poor unified maintainability. Design of a high-performance general-purpose signal processing system supporting high-consistency multi-channel signal transmission and reception
