Title:
DATA TRANSMISSION METHOD AND APPARATUS IN MULTIPLE-INPUT MULTIPLE-OUTPUT SYSTEM AND NETWORK DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/134529
Kind Code:
A1
Abstract:
Provided are a data transmission method and apparatus and a network device. The method comprises: respectively performing encoding and scrambling processing on each data stream of a plurality of data streams; performing bit-to-symbol mapping processing on each data stream on which encoding and scrambling processing has been performed; preprocessing each data stream on which the mapping processing has been performed, to obtain a data stream corresponding to each antenna of a plurality of antennas, wherein the preprocessing comprises at least one of the following: airspace matching filtering processing and inter-symbol interference elimination processing; performing single-carrier modulation processing on the data stream corresponding to each antenna; and outputting a data stream corresponding to each antenna on which the single-carrier modulation processing has been performed to a radio unit. The present invention can reduce the complexity of signal processing of a data sending end and a receiving end, reduce a PAPR of the sending end and improve a signal-to-noise ratio of the receiving end.
