摘要： An apparatus and method for merging a disjoint pair of maps comprising a digital building map that includes a floor plan and an access point (AP) map that includes identifiers for a plurality of access points is presented. In some embodiments, a first trajectory plot, of a mobile device, relative to the AP map, is received and a plurality of hypotheses is set, where each hypothesis defines a unique translation between the AP map and the building map. A plurality of costs may be computed for the first trajectory, where each cost of the first trajectory corresponds to a distinct hypothesis in the plurality of hypotheses. The hypothesis where the first trajectory has the lowest cost relative to the other hypotheses may be selected.

摘要： A system for synchronizing a receiver of a bit stream to the bit stream include a correlator to remove the PN code modulation and to generate a stream of time sequence values (samples) from the received bits. Multiple accumulators are included, each accumulator corresponding to a different offset from a first time period. The accumulators add a number of values equal to a number of samples in a bit period. Multiple magnitude calculators receive sums from the corresponding accumulators and calculates respective magnitudes. Multiple non-coherent summers are then used to add the magnitudes for each offset in each bit period for all of the received bits. The outputs of the non-coherent summers are analyzed to find the highest value, to identify the location of the bit transition in the bit period.

摘要： A system and method for synchronizing a receiver of a bit stream to the bit stream include a correlator to remove the PN code modulation and to generate a stream of time sequence values (samples) from the received bits. A plurality of accumulators are included, each accumulator corresponding to an offset in a series of time intervals starting with a first time period. The accumulators add a number of values equal to a number of samples in a bit period. The values added by each accumulator is a set of values starting with the value at the offset corresponding to the accumulator. A plurality of magnitude calculators receives a sum from the corresponding accumulator and calculates a magnitude. A plurality of non-coherent summers are then used to add the magnitudes for each offset in each bit period for all of the received bits. The total sum in each non-coherent summer is then analyzed to find the highest value, such that the offset corresponding to the non-coherent summer with the highest value represents the location of the bit transition in the bit period.
