Patent ID: 7542486

Claim:
A method for processing an incident pulsed signal of an ultra wide band type received over a channel by a data device operating in a wireless data communications system, the incident pulsed signal carrying information within a super-frame structure, each super-frame structure comprising a plurality of frames respectively allocated for communications between specific pairs of data devices operating in the wireless data communications system and a header including at least one first training sequence, each frame comprising a preamble including at least one second training sequence, the method comprising: upon reception of each super-frame structure by a data device, performing coarse synchronization with another data device acting as a coordinator device for the wireless data communications system, the coarse synchronization using the first training sequence; and upon reception of each frame allocated to the data device operating within the super-frame structure, performing channel estimation using the second training sequence, the channel estimation being based on at least one signal slice having ends temporally defined with respect to a result of the coarse synchronization, the channel estimation also performing a frame synchronization.
