The present disclosure relatespertains to a method offor encoding a data signal, aas transmitterwell andas a receiver. The method receives the data signaltransmitter and encodesreceiver thedesigned datafor signalthis by applying a dispersive delay response to the data signal thereby generating an encoded data signalpurpose. The transmittermethod comprisesinvolves at least one phaser for applying a dispersive delay response toreceiving the signal thereby generating an encoded data signal. Theand receiverencoding comprises at least one phaser for decoding the received encoded data signalit by applying an inversea dispersive delay response, toresulting thein receivedan encoded data signal.

The transmitter includes at least one phaser, which applies the dispersive delay response to generate the encoded data signal. Similarly, the receiver incorporates at least one phaser, which decodes the received encoded data signal by applying an inverse dispersive delay response.

The novel Dispersion-code Multiple Access (DCMA) and conventional [[Code-division multiple access|Code-Division Multiple Access]] (CDMA) both aim to enable multiple users to share the same communication medium simultaneously without interference. They achieve this by encoding data signals; DCMA uses dispersive delay responses to encode and decode signals, whereas CDMA employs unique spreading codes for signal separation. The primary difference lies in their encoding techniques: DCMA relies on the physical properties of dispersive structures, while CDMA depends on mathematical code sequences to distinguish between users.
