摘要: In a wireless communication network, the location of an addressable receiver relative to locations plurality sources electromagnetic radiation is found using probabilistic models signal strength measured at receiver. The inventive method provides determination on finer spatial scale than was heretofore available. A region interest calibrated via discrete-space radio map storing probability distributions received measurement locations. stored are compensated for temporal variability and biases, such as through correlations sampled strength. from each used in conjunction with identify one coordinates thereof that maximizes conditional P(xls), where x s vector strengths.
