Abstract

The present invention provides methods and systems for communication, including UWB based wireless and wired communication, in which information is transmitted utilizing a continuous series of burst symbol cycles, each burst symbol cycle including an ON period during which a number of chips representing a bit of information are transmitted using anultra-wide band signal, and an OFF period during which no signal is transmitted, providing advantages that can include scalability, adaptability and flexibility. Systems are provided that utilize the burst symbol cycle transmission technique in providing wireless and wired communication between multiple digital devices in a local area.
