Abstract: A data receiving method and receiver are provided. A receiver determines the length of a pre-tail and the length of a post-tail of a frame by obtaining a start time and an end time of the main part of the signal of the frame at a fixed time, and determines a start time and an end time of a frame receiving window according to the start time and the end time of the main part of the signal of the frame and according to the length of the pre-tail and the length of the post-tail; and receiving a frame between the start time and the end time of the frame receiving window, so that the receiver can accurately and completely receive the main part of the signal and the pre-tail and post-tail of each frame to accurately and completely receive signals.

Abstract: Embodiments of the present invention disclose a codeword feedback method and a receiver, which relate to the field of communication technologies. The method includes: determining a precoding type used for downlink signal transmission, or receiving codebook indication signaling transmitted by a transmitter; selecting a codebook according to the precoding type, or selecting a codebook according to the codebook indication signaling; and selecting a codeword according to the codebook, and feeding back the codeword to the transmitter. The present invention can provide a new feedback mechanism for channel state information and a non-linear precoding codebook when needing to use both linear precoding and non-linear precoding, so that a communication system can select an appropriate precoding codebook to feed back state information according to different needs, thereby improving the performance of the communication system.
