Equalization method in a receiver using a combination of modulation techniques of multi-carrier and code division multiple access

摘要

(57) Abstract This invention being the signal reception method which uses the union of irregularity technology of the multiplex carrier and code division multiple access, including with the equalization stage which consists of the fact that it equalizes the recovery stage which recovers by applying the mathematical conversion to the frequency domain from the time domain and the signal which is converted and the signal which is equalized the opposite spread stage which spreads conversely, regards the reception method which becomes. This invention that is the signal reception method which features that the disturbance which is influenced the aforementioned equalization stage, at least one other carrier inside the carrier and the aforementioned carrier which bear the aforementioned component the component of the aforementioned suffering conversion signal in respectively, and, at least how many among the aforementioned spread marks, is considered.
