Constructions of an Mt-mfsk Multiplexing Technique for Radio Communications with Bursty Traac

| Code division multiplexing or multiple access techniques provide a method of isolating multiuser transmissions in a non-orthogonal fashion. The communication resources are shared dynamically between users. In networks with bursty traac having a large numbers of subscribers, each having very low duty cycles, non-orthogonal channeliza-tion enables active users to exploit the shared portion of system resources from the large number of silent subscribers. Undoubtedly, the price of sharing is interference; users sharing the resources interfere each other when active at the same time. The extent of sharing limits the maximum number of simultaneous users, below which the transmissions are still decodable. This paper reports on the constructions for one particular non-orthogonal multiplexing scheme using Multi-tone M-ary FSK as both the signaling and modulation technique. The scheme is intended for synchronous intensity detection systems with bursty traac.
