In this paper, random interleaving multiplexing for random access scheme is proposed to further improve throughput and energy efficiency in satellite networks, which resort to the state-of-art physical layer techniques that can resolve multiple packet collisions. The bit and symbol level interleavers are randomly selected by active users from sets of interleavers, which are utilized to differentiate signals of different users sharing a subframe, and MAP detector can be employed to decode multiple superimposed packets. By further utilizing transmission diversity and interference cancellation technique, the proposed scheme can combine with Contention resolution diversity slotted ALOHA (CRDSA), called RIM-CRDSA protocols, and its an upper bound of throughput is derived. Simulation results show that the peak throughput of RIM-CRDSA can approach 2.0 bits/symbol, which largely outperform conventional random access protocols.
