Abstract:

A method for transmitting information by radio over a wide bandwidth comprises the steps of inputting a data signal into a time varying filter modulator spreading the data signal in time and in frequency to produce a wideband signal modulating the wideband signal onto an RF carrier to provide an RF output signal and transmitting the RF output signal. The step of spreading includes performing a series of linear transformations to the data signal.
