Abstract:
1. A receiver for ultra wideband communications, comprising: a low-gain amplifier for amplifying a spread signal received from an external transmitter to a predetermined gain level; a clock signal reproducing circuit for reproducing an input clock signal based on the amplified spread signal obtained from the low-gain amplifier; a pseudo noise code generator for generating a pseudo noise code based on the reproduced input clock signal obtained from the clock signal reproducing circuit; a correlator for demodulating the amplified spread signal obtained from the low-gain amplifier according to the pseudo noise code generated by the pseudo noise code generator; an automatic gain control amplifier for amplifying the demodulated signal obtained from the correlator to a signal having a wide dynamic range and a constant amplitude level; and a determiner for processing the amplified signal obtained from the automatic gain control amplifier to reproduce original input data contained in the spread signal.
