IMPULSE CARRIER SIGNAL REPRODUCTION DEVICE FOR ULTRA WIDEBAND RECEIVER AND ULTRA WIDEBAND RECEIVER COMPRISING SAME

摘要

The present invention relates to an ultra wideband (UWB) communication system and, more particularly, to an impulse carrier signal reproduction device capable of reproducing, at a low clock speed, an impulse carrier signal transmitted from an ultra wideband (UWB) transmission terminal, and an ultra wideband receiver comprising the same, the impulse carrier signal reproduction device comprising: an impulse carrier signal detection unit comprising a plurality of impulse carrier signal detectors, each of which is enabled or disabled in accordance with the positive and negative edges of digital impulse carrier signals which are sequentially inputted from an RF processing unit, thereby sequentially generating trigger signals; and an impulse carrier signal reproduction unit for reproducing transmission impulse carrier signals synchronized with an internal standard clock of a receiving terminal by counting the internal standard clock of the receiving terminal according to an input of a series of the trigger signals.
