Abstract: A method operational in a mobile device is provided for ascertaining location information for the mobile device by using captured/received locating information broadcast by local sensor devices. The method captures, at the mobile device, a message from a sensor device transmitted, for example, over a local wireless network. The method identifies a locating data in the message and may determine a location of the mobile device based on the identified locating data.

Abstract: Systems and methodologies are described that facilitate equalization of received signals in a wireless communication environment. Multiple transmit and/or receive antennas and utilize MIMO technology to enhance performance. A single tile of transmitted data, including a set of modulation symbols, can be received at multiple receive antennas, resulting in multiple tiles of received modulation symbols. Corresponding modulation symbols from multiple received tiles can be processed as a function of channel and interference estimates to generate a single equalized modulation symbol. Typically, the equalization process is computationally expensive. However, the channels are highly correlated. This correlation is reflected in the channel estimates and can be utilized to reduce complex equalization operations. In particular, a subset of the equalizers can be generated based upon the equalizer function and the remainder can be generated using interpolation. In addition, the equalizer function itself can be simplified.
