Implementation of a Circuit for Communication Using Solitons by Lloyd

The Toda lattice is a solvable nonlinear system which supports soliton solutions. Recently, soliton systems have been proposed for a variety of communication and signal processing applications. In this thesis, a hardware implementation of a soliton-based communication circuit is presented. The circuit comprises soliton signal generation and modulation hardware, where multiple solitons are generated and can be amplitude or phase modulated. The Toda lattice circuit is used as a nonlinear multiplexor, where multiple solitons of different wavenumbers are naturally combined by the nonlinear soliton dynamics. Demultiplexing is similarly performed by the soliton dynamics. Simple hardware is then used to demodulate the separated solitons. Thesis Supervisor: Andrew C.
