A method and system using ternary sequences for simultaneous transmission to coherent and non-coherent recievers

A method of receiving data transmitted from one or more transmitter comprising:

• receiving one or more ternary sequences transmitted from the one or more transmitter by a receiver;
• demodulating the received one or more ternary sequences using a base ternary sequence;
• and
• detecting the data transmitted from the one or more transmitter.

A transmitter comprises:

• a data input module;
• a transmitting module;
• a symbol generating module couple with the data input module for adapted for generating one or more symbols based on input data;
• and
• a ternary sequence generating module coupled with the symbol generating module,
• a base ternary sequence retrieving module and a cyclic shift generating module, wherein the base ternary sequence retrieving module retrieves one or more base ternary sequence corresponding to the generated symbols;
• and
• the cyclic shift generating module is adapted for generating cyclic shift in the base ternary sequence based on the generated symbol.

A base ternary sequence generating module comprises:

• a seed sequence selection module adapted for selecting the seed sequence as a first sequence of the preferred pair;
• and
• selecting a second sequence of the preferred pair , wherein the second sequence is pre-defined decimation of the first sequence,
• a pre-defined value insertion module.

A receiver comprising:

• a signal receiving module for receiving a signal transmitted from a transmitter;
• a demodulating module coupled with a sample sequence input module and the signal receiving module, wherein the demodulating module demodulates the received signal correlating one or more ternary sequence input from the ternary sequence input module with the received signal;
• and
• a symbol detection module is adapted for detecting one or more transmitted data-symbols based on the sequence of maximum correlation corresponding to the demodulated ternary sequence.
