Abstract

One or more embodiments of the present specification provide a signal sending method of an MIMO transmission system based on polarization transformation. A signal sending end in the MIMO transmissionsystem determines symbol streams respectively corresponding to N sending time slots according to to-be-sent data; the signal sending end can respectively determine sending symbol vectors respectivelycorresponding to the N sending time slots; the signal sending end pre-codes the modulation symbol vectors corresponding to the sending time slots according to a pre-coding codebook to obtain sending symbol vectors corresponding to the sending time slots; and the signal sending end sends the sending symbol vectors corresponding to the sending time slots to a signal receiving end in the MIMO transmission system in sequence. Thus, the embodiments of the present invention can reduce the bit error rate in the transmission process of sending the symbol vectors, thereby improving the reliable transmission of the data and the performance gain of the 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...
