Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for modulating and demodulating transpositional modulated (TM) signals. One aspect features a method of modulating a carrier signal that include the actions of generating a TM signal by generating a sinusoidal signal, and modulating the sinusoidal signal based on a data signal to provide the TM signal. Inserting the TM signal into a carrier signal to provide a TM modulated carrier signal. Modulating the TM modulated carrier signal with a non-TM signal to provide a combined signal. Transmitting the combined signal.
Claims28
A method of modulating a carrier signal, the method comprising:
- generating a transpositional modulation (TM) signal by:
- generating a sinusoidal signal;
- and
- modulating an amplitude of the sinusoidal signal based on a data signal to provide the TM signal;
- inserting the TM signal into a carrier signal to provide a TM modulated carrier signal;
- and
- transmitting the TM modulated carrier signal.
A transmitter comprising:
- at least one processor;
- and
- a data store coupled to the at least one processor having instructions stored thereon which, when executed by the at least one processor, causes the at least one processor to perform operations comprising:
- generating a transpositional modulation (TM) signal by:
- generating a sinusoidal signal;
- and
- modulating an amplitude of the sinusoidal signal based on a data signal to provide the TM signal;
- inserting the TM signal into a carrier signal to provide a TM modulated carrier signal;
- and
- transmitting the TM modulated carrier signal.
