IMPULSE CARRIER RECOVERY AND UWB RECEIVER INCLUDED THE RECOVERY

摘要

The present invention relates to an Ultra-WideBand (UWB) communication system, and more particularly to an impulse carrier signal restorer which can restore an impulse carrier signal, transmitted by an UWB transmission terminal, at a low clock speed. The present invention also relates to an UWB receiver comprising the impulse carrier signal restorer. The impulse carrier signal restorer comprises: an impulse carrier signal detection unit which includes a plurality of impulse carrier signal detectors each of which sequentially generates trigger signals while being enabled or disabled in accordance with positive or negative edges of digital impulse carrier signals sequentially input by an RF processing unit; and an impulse carrier signal restoration unit which counts a reference clock at a reception end in accordance with input of a series of the trigger signals, and restores transmission impulse carrier signals synchronized with the reference clock in the reception end.
