Abstract

One or more embodiments of this specification provide a signal transmission method for a MIMO transmission system based on polarization conversion. The signal transmission end in the MIMO transmission system determines, according to the data to be sent, the symbol streams corresponding to each of the N transmission time slots; The signal transmitting end may respectively determine the respective transmit symbol vectors corresponding to the N transmit time slots; the signal transmitting end precodes the modulation symbol vectors corresponding to each transmit time slot according to the precoding codebook, respectively, to obtain each transmit time slot. The time slots correspond to the respective transmit symbol vectors; the signal transmitting end sequentially sends the transmit symbol vectors corresponding to the respective transmit time slots to the signal receiving end in the MIMO transmission system. In this way, the present embodiment can reduce the bit error rate during the transmission process of the transmitted symbol vector, thereby improving the reliability of data transmission and the performance gain of data transmission.

Description

technical field [0001] One or more embodiments of this specification relate to the field of communication technologies, and in particular, to a signal sending and receiving method and device for a polarization conversion-based MIMO transmission system. Background technique [0002] Massive MIMO (Multiple Input Multiple Output) antenna technology is an important physical layer technology for improving system capacity in 5G. However, the antenna configuration of massive MIMO greatly increases the power consumption of the system, making it difficult to meet the requirements of 5G green communication methods. Therefore, massive MIMO solutions with high rate, low latency, and low power consumption have become a research hotspot. [0003] Polar Code, as the only channel coding technology that can theoretically prove to reach the Shannon limit and has practical linear complexity coding and decoding capabilities, has become a strong candidate for the channel coding scheme in the ne...
