Abstract:
1. A method of processing a signal in a wireless digital communications system, wherein a source of non-stationary disturbance is present, said source having first statistics over a first time interval causing a first, less affected time portion of said signal received on a wireless channel, and second statistics over a second time interval, causing a second, most affected portion of said signal received on said wireless channel, the method comprising: identifying the second time portion of the received signal, most affected by the source of disturbance; generating a first estimate of the disturbance (P generating a second estimate of the disturbance (P generating reliability information for use in a decoding process, said reliability information indicating a level of reliability for transmitted data bits corresponding to the received signal samples, wherein the step of generating uses the first and second disturbance estimates whereby the bits corresponding to samples in the second most affected time portion have lower reliability estimates than samples in the first less affected time portion and thereby carry less weight during the decoding process.
