Abstract
A method (600), device, wireless transceiver, computer and personal digital assistant (300, 400) provide collision presence detection in wireless intensity-modulated binary-coded data transceivers which is compatible with the collision detection employed in IEEE standard 10BASE-T Ethernet. A measurement of the degree of correlation which exists between the signal transmitted and the signal received provides a basis for efficient collision detection in CSMA systems.
