Abstract
A transmitter configured to communicate a data chirp signal to a receiver, the chirp signal comprising at least one symbol, each symbol comprising one or more identical chirps, each symbol having a different gradient to another symbol in the chirp signal, each chirp encoding a symbol value, the transmitter comprising: an address encoding module configured to encode an address associated with the communication via the sequence of gradients of the symbols in the chirp signal; a data encoding module configured to encode data in the chirp signal via the symbol value of each chirp; and a transmitting module configured to transmit the data chirp signal to the receiver.

A transmitter configured to communicate a data chirp signal to a receiver, the chirp signal comprising at least one symbol, each symbol comprising one or more identical chirps, each symbol having a different gradient to another symbol in the chirp signal, each chirp encoding a symbol value, the transmitter comprising:
- an address encoding module configured to encode an address associated with the communication via the sequence of gradients of the symbols in the chirp signal;
- a data encoding module configured to encode data in the chirp signal via the symbol value of each chirp;
- and
- a transmitting module configured to transmit the data chirp signal to the receiver.
A receiver configured to receive a data chirp signal from a transmitter, the chirp signal comprising at least one symbol, each symbol comprising one or more identical chirps, each symbol having a different gradient to another symbol in the chirp signal, each chirp encoding a symbol value, the receiver comprising:
- a receiving module configured to receive the data chirp signal from the transmitter;
- an address decoding module configured to decode an address associated with the communication from the sequence of gradients of the symbols in the chirp signal;
- and
- a data decoding module configured to decode data in the chirp signal from the symbol value of each chirp.
A method of communicating a data chirp signal to a receiver, the chirp signal comprising at least one symbol, each symbol comprising one or more identical chirps, each symbol having a different gradient to another symbol in the chirp signal, each chirp encoding a symbol value, the method comprising:
- at the transmitter, encoding an address associated with the communication via the sequence of gradients of the symbols in the chirp signal;
- at the transmitter, encoding data in the chirp signal via the symbol value of each chirp;
- and
- transmitting the data chirp signal to the receiver.
