Problems solved by technology

In existing communication systems, a fixed interleaving method is commonly used, which cannot meet the system requirements in the face of high-speed data transmission in fading channels.
Adaptive interleaving rules can disperse error bits to the greatest extent, improve system decoding success rate, and improve system performance, but there is no device using such interleaving rules in the prior art

Abstract

The invention discloses a multi-dimensional dynamic interweaving device for multi-antenna scattering communication, which belongs to the technical field of wireless communication and scattering communication. The present invention performs adaptive coding modulation, interleaving, space mapping, frequency conversion, and amplification at the sending end to realize the conversion from baseband channel to analog signal; The proportional relationship and distribution relationship between the channel quality and SNR of each channel can be obtained; then the dynamic interleaving rule planner can be used to obtain the interleaving / deinterleaving matrix, and finally the optimization of the interleaving and deinterleaving rules can be realized, which can increase the bit error rate by 2 order of magnitude to achieve a good transmission effect. The invention can be used for high-speed information transmission under the fading channel beyond the line of sight, and is especially suitable for a multi-antenna scattering communication system with multiple transmission and multiple reception.

Description

technical field [0001] The invention relates to the technical field of wireless communication and scattering communication, in particular to a multi-dimensional dynamic interweaving device for multi-antenna scattering communication, which can be used in a multi-antenna communication system with multiple transmitting antennas and multiple receiving antennas. Background technique [0002] A multi-antenna communication system is a communication system that uses multiple transmitting antennas and multiple receiving antennas. It is mainly used to enhance the effect of the communication system, and its value has been widely recognized in wireless communication networks. [0003] In communication systems, interleaving is used to break up data, and it is used in combination with error correction coding to solve burst error codes during information transmission. In existing communication systems, a fixed interleaving method is commonly used, which cannot meet the system requirements ...
