Permutation modulation for advanced radio paging

A multicarrier permutation modulation technique is proposed which provides higher bit rates and spectrum efficiencies than those achieved in any state-of-the-art radio paging system. It can be used in simulcast networks with high power transmitters, where long symbol intervals and noncoherent detection are required. The technical feasibility of the proposed modulation technique is established through a set of laboratory and field experiments. Variations of the proposed modulation technique are discussed with regard to the performance and complexity of receivers and transmitters
