A new efficient chirp modulation technique for multi-user access communications systems

In this paper, we present a novel chirp modulation technique that completely suppresses the interference between the users in a multi-access communications system. The interference suppression is obtained by using an orthogonal set of chirp signals in the proposed modulation scheme. Simulation resul...

Description
Summary:In this paper, we present a novel chirp modulation technique that completely suppresses the interference between the users in a multi-access communications system. The interference suppression is obtained by using an orthogonal set of chirp signals in the proposed modulation scheme. Simulation results, based on Monte-Carlo realizations, show that the new technique can easily handle a larger number of users, compared to existing techniques, without a degradation in performance.
