Patent Images
1. A method for adapting to rapid changes affecting a wireless signal of a wireless communication link between a first station and a second station, the method comprising:
- receiving, by the first station, a measurement of amplitude variance of the wireless signal;
determining, by the first station, a rapid change in the wireless signal by comparing the measurement to a predetermined threshold;
selecting, by the first station, a parameter adjustment from a plurality of parameters related to the wireless signal, based on the determined rapid change; and
performing, by the first station, the parameter adjustment.

Abstract
A mobile station measures at least one modulation attribute of at least one signal transmitted across a signaling path of a wireless link between the stations. Because the signal travels on the signaling path between the stations, rapid changes in the modulation attribute can be used to determine both (i) motions of the mobile station and (ii) changes in the base station or mobile station environments. The stations adjust at least one parameter affecting the performance of the wireless link to compensate for the rapid changes.
