Abstract: Embodiments of the present invention provide a channel encoding and decoding method and apparatus, where a channel encoding method includes: acquiring, by an encoder, an information bit index set; generating, by the encoder, a second bit vector according to a to-be-encoded first information bit and the information bit index set; and performing, by the encoder, Polar code encoding on the second bit vector to generate an encoded first code word. In technical solutions of the present invention, an encoder first acquires an information bit index set, generates a second bit vector according to a to-be-encoded first information bit and the information bit index set, and then performs Polar code encoding on the second bit vector to generate an encoded first code word.

Abstract: Disclosed are a distributed multi-cell multi-user beamforming method, a transmitter and a relevant system. In the distributed beamforming method in the embodiments of the present invention, beamforming coordinated calculation is performed by a plurality of transmitters, and an interference matrix among the transmitters is used to perform an iterative operation on a beamforming vector corresponding to the data which is to be sent to each user over each sub-channel of this cell, so that the interference dimension of each user over each sub-channel of the transmitters is compressed into a subspace as small as possible.
