Abstract:
1. A method for receiving signals in a wireless communication system, the method comprising: computing at a first wireless device, at least one phase difference value between at least one current received symbol and a corresponding at least one previous received symbol; computing at said first wireless device, at least one weighted sum of a plurality of absolute values of said computed at least one phase difference value; computing at said first wireless device, at least one differential phase value based on at least one or both of: said computed at least one weighted sum and a previous said at least one differential phase value, wherein said computed at least one differential phase value is communicated to a second wireless device; and upon receiving from said second wireless device, data responsive to said at least one differential phase value communicated to said second wireless device, configuring an operating mode of said first wireless device based on said data received from said second wireless device.
