Abstract

The invention provides a data receiving method and device in a multipoint-to-point system, electronic equipment and a storage medium. The method comprises the following steps: receiving and caching OFDM signals transmitted based on a certain number of sub-channels; respectively determining corresponding channel characteristics for the sub-channels according to the reference signals of the sub-channels; dividing all the sub-channels into at least two sub-channel groups; wherein each of the sub-channel groups comprises at least one of the sub-channels; and on the basis of the OFDM signal, sequentially carrying out demodulation processing on the sub-channel groups according to a predetermined sequence, so as to obtain data transmitted by the sub-channels included in the corresponding sub-channel groups after each demodulation processing. According to the scheme provided by the invention, the problems of ICI, ISI and masking effect in the data receiving process of the multi-point-to-point system can be effectively avoided, and the performance of the receiver is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a data receiving method, apparatus, electronic device and storage medium in a multipoint-to-point system. Background technique [0002] At present, wireless communication systems based on Orthogonal Frequency Division Multiplexing (OFDM) technology are widely used in daily life. In some application scenarios, the receiver of the OFDM system needs to be in one channel bandwidth (Channel BandWidth, CBW; for 5G, it can be BWP, BandWidthPart), and simultaneously receive data sent by multiple users in different sub-channels (Sub-Channel) . An OFDM system with the above-mentioned characteristics is a so-called multipoint-to-point (N-to-1) system. [0003] For the multi-point-to-point system in the related art, severe inter-carrier interference (Inter-Carrier Interference, ICI), Inter-Symbol Interference (ISI), and masking effects generally exist, which affect ...
