First Claim
Patent Images
1. A hearing device comprising:
- a processing unit;
a filter; and
a wireless receiver;
wherein the processing unit is configured to determine a time difference between a start of the wireless receiver and a reception of a corresponding data packet from a transmitter;
wherein the filter is configured to determine a time period as a function of a plurality of time differences that include the time difference determined by the processing unit;
wherein the processing unit is further configured to control the wireless receiver such that the wireless receiver is started in the time period before reception of a subsequent data packet from the transmitter;
wherein the filter comprises a plurality of taps configured to receive the plurality of time differences; and
wherein the function is associated with the determined time difference and a number of lost data packages since a last successful data packet reception.

12. A method of compensating a frequency difference between a wireless receiver and a transmitter, the method comprising:
-
determining a time difference between a start of the wireless receiver and a reception of a corresponding data packet from the transmitter; receiving a plurality of time differences by a plurality of taps, respectively, wherein the taps are parts of a filter, and wherein the plurality of time differences includes the determined time difference; determining a time period based on a function that is associated with the determined time difference and a number of lost data packages since a last successful data packet reception; and starting the wireless receiver in the time period before reception of a subsequent data packet from the transmitter. - View Dependent Claims (13, 14, 15, 16, 17)
