First Claim
Patent Images
1. A signal processing method for reducing discrete components of an Ultra Wideband signal that includes source data having a repetitive component, the method comprising the steps of:
- scrambling at least a portion of the repetitive component of the source data;
inverting portions of the source data including at least portions of the repetitive component according to a predetermined inverting function; and
preparing the scrambled and inverted source data for transmission.

Abstract
Methods and apparatus for reducing discrete components of an Ultra Wideband (UWB) signal that includes source data having a repetitive component are disclosed. The discrete components are reduced by scrambling at least a portion of the repetitive component of the source data, inverting the source data according to a predetermined inverting function, and preparing the scrambled and inverted source data for transmission.
