MULTIPLE ACCESS TECHNIQUES FOR A WIRELESS COMMUNIATION MEDIUM
First Claim
1. A multiple access method for a transmitted reference system, comprising:
- defining at least one first delay period between a reference pulse and a data pulse associated with a first channel; and
providing a reference pulse and a data pulse separated in time in accordance with the at least one first delay period;
wherein the at least one first delay period is different than at least one second delay period associated with a second channel of the transmitted reference system.

Abstract
A multiple access technique for a wireless communication system establishes separate channels by defining different time intervals for different channels. In a transmitted reference system different delay periods may be defined between transmitted reference pulses and associated data pulses for different channels. In addition, a multiple access technique may employ a common reference pulse for multiple channels in a transmitted reference system. Another multiple access technique assigns different pulse repetition periods to different channels. One or more of these techniques may be employed in an ultra-wide band system.
