Mapping radio-frequency noise in an ultra-wideband communication system
First Claim
1. A method for estimating channel quality in a multi-channel ultra-wideband communication system, the method comprising the steps of:
- pseudo-randomly placing a plurality of time bins within a plurality of time frames, each time bin comprising one or more data bits;
assigning a plurality of channels comprising selected pseudo-randomly placed time bins;
transmitting a multiplicity of data bits through the plurality of channels;
monitoring the number of data bits transmitted through each channel;
determining a number of data bit errors in the transmissions;
determining a projected bit error rate for at least one transmission; and
grading a channel quality using at least the projected bit error rate.

Abstract
A system and method for mapping, radio-frequency (RF) noise, and estimating channel quality in a multi-channel ultra-wideband communication system is provided. One method includes placing a plurality of time bins within a plurality of time frames and assigning a plurality of UWB communication channels comprising selected time bins. RF noise amplitude data is then sampled from selected time bins. The sampled RF noise amplitude data from the time bins is then averaged, thereby obtaining an average RF noise amplitude in each of the plurality of channels. The RF noise amplitude indicates the amount of RF noise present in a channel. The channels may then be ranked based on the characteristics of the RF noise.
