Document Type and Number:
WIPO Patent Application WO/2024/057817
Kind Code:
A1
Abstract:
[Problem] To provide a wireless signal processing system and a wireless signal processing method for implementing an iterative MUD which makes it possible to shorten calculation time. [Solution] This wireless signal processing system is characterized by comprising: an error calculation means for generating two or more patterns of estimated signals for which the waveform is estimated for each of transmission signals transmitted from two or more second communication stations, and for respectively calculating an estimation error based on the difference between the received signal and the sum of the estimated signals included in the respective generated patterns; a selection means for selecting two or more of the estimated signal patterns on the basis of the respective estimation errors calculated by the error calculation means; a probability calculation means for calculating a probability distribution indicating the distribution of the probability that the estimated signal is the transmission signal, on the basis of the estimation error with respect to the two or more patterns selected by the selection means; and an estimation means for estimating information included in the transmission signal on the basis of the probability distribution calculated by the probability calculation means.
