Abstract
Official abstract text for this publication.
A speed parameter or channel quality parameter are determined in a mobile device based on variation in frequency offset measurement. A higher variation in the frequency offset measurement reflects a poorer channel quality and a higher speed; a lower variation in the frequency offset measurement reflects a better channel quality and a lower speed. The parameter(s) may be fed back to the system and used, for example, to make adaptive modulation and coding decisions.
First claim
Opening claim text (preview).
We claim: 1. A method comprising: receiving a signal over a wireless communications channel; making a plurality of frequency offset measurements in respect of the signal; estimating a PDF of the frequency offset measurements; determining at least one of a channel quality parameter and a speed parameter as a function of the PDF; determining the measure of variation from the PDF. 2. The method of claim 1 wherein determining at least one of a ch…
