INTERACTIVE WIRELESS COMMUNICATION DEVICE

摘要

One communication apparatus 2 sequentially generates a pulse sequence having pulse signals arranged based on the UWB communication system, performs a framing process to form a frame having at least a preamble and a data portion on the generated pulse sequence and inserts a preamble segment comprised of a sequence of steady pulse signals in the data portion at a predetermined time interval, and transmits it as a radio wave, and another communication apparatus 2 receives a pulse sequence as a radio wave transmitted from the one communication apparatus 2, and detects at least the preamble segment from the frame contained in the received pulse sequence through a detection window structured to have a predetermined time length, whereby a transmission timing for the pulse sequence to the one communication apparatus 2 is controlled according to a state of detection of the preamble segment.
