Embodiment Construction

[0099] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0100] The technical solution of the present invention is mainly applied to a multi-carrier system using multi-carrier technology, especially a multi-carrier system that only satisfies the orthogonal condition in the real number domain, such as an FBMC (Filter Bank Based Multicarrier, filter bank multi-carrier) system, which Because of its advantages such as good out-of-band suppression, high spectrum utilization, and flexible spectrum use, it is called one of ...

Abstract

The embodiments of the invention provide a data sending and receiving method, device, and equipment. The sending end determines M first time-frequency resource locations and S second time-frequency resource locations, and among the S second time-frequency resource locations, S / 2 second time-frequency resource positions are the first set, and S / 2 second time-frequency resource positions not including the second time-frequency resource positions in the first set are the second set; The communication data symbol sent by the second time-frequency resource position, and calculate the compensation data symbol sent by the second time-frequency resource position in the second set according to the communication data symbol, and the communication data symbol and the compensation data symbol pair The interference of the pilot data symbols is cancelled; the pilot data symbols, the communication data symbols and the compensation data symbol. The embodiments of the present invention can obtain more accurate channel estimation values.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically relates to a data sending method, a data receiving method, a data sending device, a data sending device, a data receiving device and a data receiving device. Background technique [0002] In wireless communication systems, communication data will be distorted after passing through the channel. In order to resist the influence of the wireless channel on the transmitted data, channel estimation at the receiving end is essential. In a multi-carrier system, a pilot-based channel estimation scheme is usually used. The pilot is known data. The pilot is sent by the transmitting end, and the receiving end implements channel estimation based on the received data at the pilot sending position. [0003] However, the inventor found in the research that in a multi-carrier system, especially a system that only satisfies the orthogonality condition in the real number domain,...
