Abstract
Systems, methods and devices for transmitting and receiving and demodulating transpositional modulated signals, for increasing information bandwidth of defined communication channels, and for time-delay shifting an input signal in accordance to an input control signal are provided. One such method of increasing the information bandwidth of a defined communication channel includes receiving a first modulated signal having a first carrier signal frequency; receiving a second modulated signal having a second carrier signal frequency, the second modulated signal being modulated with information independent of information modulating the first carrier signal, the second carrier signal frequency being harmonically or sub-harmonically related to the first carrier signal frequency; and combining the first and second signals.

18. A transmitter comprising:
-
a modulator that is configured to modulate a carrier signal to carry data using transpositional modulation (TM); and a TM selector coupled to the modulator, the TM selector configured to selectively pass a TM modulated carrier signal from the modulator to an antenna. - View Dependent Claims (19, 20, 21, 22, 23, 24)
