Description

technical field [0001] The invention relates to the field of digital signal processing, in particular to a method for realizing ultra-wideband and multi-board multi-channel synchronous transmission based on an FPGA single board. Background technique [0002] With the continuous development of software radio technology and array signal processing technology, the amount of real-time processing data required for signal processing is gradually increasing, which makes the accurate and synchronous transmission of data streams face greater challenges. In the past, the system used high-speed transmission to transmit multiple data streams, and it was very difficult to accurately synchronize the signals, resulting in disorder after the transmission data was combined. [0003] With respect to the related technologies mentioned above, the inventor believes that there is a bottleneck problem in the connection, therefore, a technical solution needs to be proposed to improve the above tech...
