摘　　要：现有技术在处理多通道并行接收数据的同步捕获时,通常采用全精度计算,由于计算复杂,通常需要消耗大量的片上资源,当数据为多通道并行接收数据时,其资源消耗通常是单通道资源消耗的整数倍,这导致了在资源紧张的情况下捕获过程无法正确实现。为了解决以上资源消耗问题,提出了一种基于多通道并行接收的同步捕获及速率判决方法,在利用较少硬件资源实现多通道并行捕获的同时,基于快速速率识别算法,实现速率识别。When multi-channel parallel received data are captured synchronously by using the exist-ing technologies,full-precision calculation is usually adopted,which usually consumes a large a-mount of on-chip resources due to the complexity of the calculation.The data is multi-channel par-allel received data,so the resource consumption is usually an integer multiple of the single-channel resource consumption,which leads to the capture process not being properly implemented under re-source constraints.In order to solve the above resource consumption problems,this paper proposes a synchronous capture and rate judgment method based on multi-channel parallel reception,which achieves rate recognition based on a fast rate recognition algorithm while fewer hardware resources is used to achieve multi-channel parallel capture.
