摘要： Wireless communication devices are disclosed that are capable of selecting and changing signal polarities depending on channel conditions in order to improve or optimize communication therebetween. When a first polarization direction is deemed inadequate, the devices can switch to communicating via a second polarization. In addition, information relating to received signal qualities in the different polarizations can be stored in each device to allow for quick and efficient exchanges between configurations. Finally, when conditions warrant, the devices can enter a dynamic polarization configuration in which signal polarizations are switched rapidly so as to enjoy benefits of diversity.

摘要： A wireless transmitter is disclosed that is capable of pre-compensating for oscillator phase noise. In the transmitter, an undesired phase noise being generated by a voltage-controlled oscillator can be detected by comparing the output of the voltage-controlled oscillator to a reference oscillator output. The phase can then be detected by calculating a desired number of zero crossings over a given time period, and comparing this value to an actual number of zero crossings detected in the signal generated by the voltage-controlled oscillator over the same period. From this, the phase component can be determined and digitally pre-compensated in a data signal.
