1. A method for mitigating specular reflections, the method comprising:
by a wireless device:
measuring one or more fading properties of a signal received from a satellite, the signal including a direct path component and a specular reflected indirect path component;
comparing the one or more measured fading properties of the signal to at least one fading criteria; and
when the comparing satisfies the at least one fading criteria, configuring a wireless transceiver of the wireless device to operate in an adaptive mode that comprises alternating high performance time periods and low performance time periods.
