Abstract
Various embodiments comprise systems, methods, architectures, mechanisms and apparatus for undersea transmission using a Zero-Correlation-Zone (ZCZ) signal with an auto-correlation function having a zero-sidelobe zone, wherein modulated data is mapped to circular time shifts in ZCZ signals for transmission, and wherein periodic cross-correlation function peaks of received ZCZ signals are detected to enable thereby recovery of the circular time shifts in the received ZCZ signals in the time domain.
Claims20
A method of communication, comprising:
- converting input data into decimal values in accordance with Zero-Correlation-Zone (ZCZ) mapping;
- modulating the ZCZ mapped decimal values in accordance with Circular Time Shift Modulation (CTSM);
- and
- transmitting the CTSM modulated signal.
An apparatus comprising:
- a Circular Time Shift Modulation (CTSM) transmitter configured for generating a CTSM signal for transmission, the CTSM transmitter comprising:
- a binary-to-decimal converter, for converting input data into decimal values in accordance with Zero-Correlation-Zone (ZCZ) mapping;
- and
- a circular time shift mapper, for modulating the ZCZ mapped decimal values in accordance with a Circular Time Shift Modulation (CTSM) scheme.
A method of wireless communication, comprising:
- converting input data into decimal values in accordance with Zero-Correlation-Zone (ZCZ) mapping;
- modulating the ZCZ mapped decimal values in accordance with Circular Time Shift Modulation (CTSM);
- and
- transmitting the CTSM modulated signal via a wireless transmission device.
