摘要： Angle of arrival and/or range estimation within a wireless communication device. Appropriate processing of communications received by a wireless communication device is performed to determine the angle of arrival of the communication (e.g., with respect to some coordinate basis of the wireless communication device). Also, appropriate processing of the communications may be performed in accordance with range estimation as performed by the wireless communication device to determine the distance between the transmitting and receiving wireless communication devices. There are two separate modes of packet processing operations that may be performed: (1) when contents of the received packet are known, and (2) when contents of the received packet are unknown. The wireless communication device includes a number of antenna, and a switching mechanism switches from among the various antennae capitalizing on the spatial diversity of the antennae to generate a multi-antenna signal.

摘要： Aspects of a method and system for simultaneous signal transmission on multiple selected frequencies may include generating from a single baseband signal, a plurality of radio frequency transmission signals each at a different radio frequency, wherein the single baseband signal comprises an in-phase signal component and/or a quadrature signal component. The single baseband signal, to generate said plurality of radio frequency transmission signals, may be modulated in a single radio frequency transmission chain, the radio frequency transmission chain comprising intermediate frequency modulation and radio frequency modulation. The plurality of radio frequency transmission signals may be a radio frequency signal and a corresponding image frequency signal, based on the intermediate frequency modulation and the radio frequency modulation. The signals resulting from the intermediate frequency modulation and the radio frequency modulation may be filtered to preserve the radio frequency signal and the corresponding image frequency signal.

摘要： A method for temperature compensation of transmit power of a wireless communication device begins by measuring transmit power of the wireless communication device at a first temperature-based biasing condition to produce a first measured transmit power. The method continues by measuring transmit power of the wireless communication device at a second temperature-based biasing condition to produce a second measured transmit power. The method continues by determining ambient temperature of at least a portion of the wireless communication device based on the first and second measured transmit powers and a relationship between the first and second temperature-based biasing conditions. The method continues by compensating transmit power level of the wireless communication device based on the ambient temperature.
