Transpositional modulation systems, methods and devices
First Claim
1. 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.

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.

8. A receiver comprising:
-
an antenna; and a transpositional modulation (TM) signal detector coupled to the antenna, the TM signal detector being configured to; receive, from the antenna, a signal; detect a presence of transpositional modulation in the signal received by the antenna; and in response to detecting the presence of transpositional modulation in the received signal, generating an output signal indicating that transpositional modulation is present in the received signal. - View Dependent Claims (9, 10, 11)

12. A method of operating a transpositional modulation signal receiver, the method comprising:
-
receiving a first signal; detecting a presence of transpositional modulation in the first signal; and in response to detecting the presence of transpositional modulation in the received signal, generating a second signal that indicates the presence of transpositional modulation in the first signal. - View Dependent Claims (13, 14)
