Ultra wideband receiver
First Claim
Patent Images
1. An ultra wideband receiver comprising:
- an antenna;
a band pass filter coupled to the antenna to provide a filtered signal;
a Xn or eX block coupled to the filtered signal, wherein the Xn block raises the filtered signal to an integer power (n) greater than one, and wherein the eX block raises a constant (e) to a power, the power having a value determined by the filtered signal;
an integration and dump block coupled to the Xn or eX block, wherein the integration and dump block has an integration time less than or equal to half a time period assigned to each data symbol; and
a decision block coupled to the integration and dump block.

Abstract
An ultra-wideband (UWB) receiver utilizing an Xn(n>1) device as a signal detector for short pulse(s), impulse(s) or ultra-wideband signal(s). The transmitted signal comes to antenna and passes through a band pass filter (BPF). The signal is fed into an Xn device. The output signal from the Xn device is fed into integration/dump block. The output from the integration/dump block is fed into decision block.

9. An ultra wideband receiver comprising:
-
an antenna; a band pass filter coupled to the antenna; a rectifier or envelope detector coupled to the band pass filter to provide a rectified signal; a Xn or eX block coupled to rectified signal, wherein the Xn block raises the rectified signal to an integer power (n) greater than one, and wherein the eX block raises a constant (e) to a power, the power having a value determined by the rectified signal; an integration and dump block coupled to the Xn or eX block, wherein the integration and dump block has an integration time less than or equal to half a time period assigned to each data symbol; and a decision block coupled to the integration and dump block. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
