Abstract

A receiver for ultra-wideband communications is provided. One feature of the receiver architecture is that includes only a single correlator. The receiver may be used in wireless and wire communication mediums. The single correlator may be used to update a locally generated signal based on an incoming signal and detect data. Another embodiment receiver may be used in a multi-path environment. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

Claims

1. An ultra-wideband pulse receiver, comprising:

two receivers structured to receive an incoming ultra-wideband pulse;

a selector switch structured to selectively receive a signal from either of the two receivers;

a pulse level quantizer structured to receive a signal from the selector switch; and

a digital signal processor structured to receive the signal from the pulse level quantizer;

wherein the digital signal processor compares a signal level received by each of the two receivers, and selects a highest signal level for forwarding to the pulse level qantizer.
