US Patent 7924949 Advanced multi-sensor processing

Each receiving node (120) of a plurality of receiving nodes (120-1, 120-2 and 120-3) in a wireless network converts a superposition of signals received from a plurality of transmitting nodes (10) to produce soft complex signal information. The soft complex signal information associated with the considered plurality of receiving nodes are collected, and jointly detect signal information transmitted from at least a subset of the plurality of transmitting nodes (10) based on the collected soft complex signal information. The collected soft signal information generally retains phase and amplitude information, and the transmitted signals are preferably detected in a joint detection process based on a complex channel representation and collected soft signal information.
