  • Publication number: 20250192919
    Abstract: This application provides a rate matching method and a communication apparatus. A transmit end punctures an LDPC codeword based on a priority order of check bits of a mother code of an LDPC code. The priority order of the check bits of the mother code indicates a priority order of puncturing the check bits in a rate matching process, and the priority order is related to confidences of the check bits. The confidences of the check bits indicate degrees to which the check bits are affected by noise in a channel transmission process. In addition, puncturing the check bits can ensure restorability of a system variable node, and a check bit with a higher confidence is more likely to be correctly restored, so that more valid information can be provided for another system variable node during decoding iteration.

  • Publication number: 20240089152
    Abstract: An angular domain channel estimation method based on matrix reconstruction for a symmetrical nonuniform array is a combined two-stage channel estimation and channel equalization scheme provided based on an SNLA model. In a first stage, a matrix reconstruction method is used to estimate a path AOA, and compared with traditional channel estimation based on ULA, the matrix reconstruction method achieves a higher resolution ratio. In a second stage, an LS method is used to obtain a path gain. According to the angular domain channel estimation method, a mean square error of channel estimation, a bit error of data transmission and complexity of a traditional scheme are significantly reduced. A simulation result indicates that compared with the traditional method, the angular domain channel estimation method can achieve a lower MSE and BER.
