The interleaving technology concatenated with the Reed-Solomon code in data transmission link has become a recommended standard of aerospace communications by Consultative Committee of Space Data System (CCSDS). But the traditional parallel structure has the problem of serious resource waste and less flexibility. In order to solve the problem, this paper puts forward an improved structure which can flexibly switch between different interleaving depths and realizes it in Field Programmable Gate Array (FPGA), thus improving the flexibility of data processing and reducing the occupying rate of valuable hardware resources.
