Optimized HiperLan2 frame reception system detects burst end in Fresnel plane

摘要

An optimized HiperLan2 frame reception system demodulates (EC330) the OFDM (Orthogonal Frequency Division Multiplexing) modulation to give a two carrier amplitude modulated signal that is demodulated (EC340) to give a signal constellation that is analyzed (EC360) in the Fresnel plane for detection (EC370) of the end of a burst when all points are within a set radius. Includes an Independent claim for mobile and base stations using the system.
