Abstract: A method for generating radio tomographic images is provided. A plurality of transceivers positioned around a region to be imaged is divided into a plurality of pixels. A control apparatus is configured to cause each of the plurality of transceivers in turn to send a signal to each of the other transceivers. The control apparatus is further configured to determine an attenuation in the received signals, generate weighing, derivative, and attenuation matrices from the signals, group the pixels into a plurality of provinces, select each province in turn and solve for a change in attenuation in each of the pixels while setting the pixels in other provinces to zero, aggregate solutions from each of the provinces into a rough estimate, re-solve each province using the aggregated rough estimate, aggregate the re-solved solutions from each province into a refined estimate, and generate an image from the refined estimate.

Abstract: A multicarrier modulation position determination method that includes deploying at least one known receiver with a known location and a second receiver with an unknown location. At least two signals of opportunity with different locations are obtained by both the receiver and the second receiver. The signals having a plurality of block data, the block data having block boundaries. The block boundaries including a beginning block boundary and an end block boundary. The block data further including a cyclic prefix at the beginning block boundary. Acquiring a plurality of data samples for at least a portion of the block data and correlating the attained signal of opportunity between the receivers. The correlating process includes the calculation of a time difference of arrival between the known receiver and the second receiver. The time difference of arrival is calculated by aligning the block boundaries and computing a single scalar statistical feature associated with each block.

Abstract: A method for equalizing data and systems utilizing the method. The method of this invention for equalizing (by shortening the channel response) data includes minimizing a function of the data and a number of equalizer characteristic parameters, where the function utilizes auto-correlation data corresponding to equalized data.
