A novel multi-services transmission scheme based on multi-chirp-rate CSS was proposed, which provided different quality of transmission to services on the physical layer. Using fractional fourier transform (FrFT), signals of different services could be recognized and classified. Multi-services transmission problem had been simplified into transform domain multiplexing/multiple access design and suppress the interference of other different service signals. By the collaborative design of services frequencies and time slots, and application of filtering in transform domain, the problem of services signals interference had been settled.
