Embodiments of the present invention disclose an electronic equalization and electronic depolarization method, a receiving end equipment, and a communication system. According to the embodiments of the present invention, parameters required by electronic equalization and electronic depolarization are calculated by detecting a Synchronization Sequence (SS) in a received signal, and then the electronic equalization and the electronic depolarization are performed on the received signal in a frequency domain by utilizing the parameters, so as to solve a problem of the electronic equalization and the electronic depolarization in a Polarization Division Multiplexing (PDM) Orthogonal Frequency Division Multiplexing (OFDM) system. Furthermore, the realization complexity of the electronic equalization and the electronic depolarization performed in the frequency domain is greatly reduced relative to the electronic equalization and the electronic depolarization performed in a time domain.

L'invention concerne, selon des modes de réalisation, un procédé d'égalisation électronique et de dépolarisation électronique, un terminal de réception et un système de communication. Selon les modes de réalisation de l'invention, les paramètres requis pour l'égalisation électronique et la dépolarisation électronique sont calculés par détection d'une séquence de synchronisation dans un signal reçu puis utilisés pour appliquer l'égalisation électronique et la dépolarisation électronique au signal reçu dans le domaine fréquentiel, en résolvant ainsi le problème posé par l'égalisation électronique et la dépolarisation électronique dans un système OFDM à multiplexage par répartition en polarisation. L'invention permet de réduire sensiblement la complexité de l'égalisation électronique et de la dépolarisation électronique mises en uvre dans le domaine fréquentiel par rapport au domaine temporel.
