Abstract
A receiver device receives a constant envelope signal and demodulates the signal to produce a demodulated baseband signal. The receiver device transforms the demodulated baseband signal into in-phase and quadrature data points, and applies an inverse unitary braid division multiplexing transform to produce transformed symbols. The receiver device also decodes the transformed symbols to produce data carried by the received constant envelope signal.
Claims15
A method comprising:
- demodulating a received constant envelope signal to produce a demodulated baseband signal;
- transforming the demodulated baseband signal into in-phase data points and quadrature data points;
- transforming the in-phase data points and quadrature data points using an inverse unitary braid division multiplexing transform to produce transformed symbols;
- and
- decoding the transformed symbols to produce data carried by the received constant envelope signal.
An apparatus comprising:
- a wireless receiver configured to receive wireless signals;
- and
- a processor configured to:
- demodulate a received constant envelope modulated signal to produce a demodulated baseband signal;
- transform the demodulated baseband signal into in-phase data points and quadrature data points;
- transform the in-phase data points and quadrature data points using an inverse unitary braid division multiplexing transform to produce transformed symbols;
- and
- decode the transformed symbols to produce data carried by the received constant envelope modulated signal.
One or more non-transitory computer readable storage media encoded with software comprising computer executable instructions and, when the software is executed on a processor of a receiver device, operable to cause the processor to:
- demodulate a received constant envelope modulated signal to produce a demodulated baseband signal;
- transform the scaled signal into in-phase data points and quadrature data points;
- transform the in-phase data points and quadrature data points using an inverse unitary braid division multiplexing transform to produce transformed symbols;
- and
- decode the transformed symbols to produce data carried by the received modulated signal.
