Abstract

The invention provides a terahertz communication system based on an RS/LDPC encoding technology, which comprises a transmitting end and a receiving end, wherein the transmitting end is used for transmitting a complete data frame comprising an encoding data packet according to a communication transmission protocol, and the encoding data packet is encoded through an RS/LDPC encoding mode and is composed of data bits and parity bits; and the receiving end is used for receiving the complete data frame, analyzing the complete data frame and extracting and recovering original data from the encoding data packet according to an RS/LDPC decoding algorithm. Compared with a terahertz communication system with no channel encoding technology, the terahertz communication system based on the RS/LDPC encoding technology provided by the invention gets several times performance enhancement, the transmission rate can reach more than Gbps, and the communication distance is significantly enhanced. Besides, the excellent encoding mode such as an LDPC code can significantly resist fading of the channel, the bit error rate is reduced, and the comprehensive performance of the system is improved. The system of the invention has a simple structure, can greatly improve and enhance the performance of the terahertz communication system, and has broad application prospects in the field of the terahertz communication technology.

Description

technical field [0001] The invention belongs to the technical field of terahertz communication, in particular to a terahertz communication system based on RS / LDPC coding technology. Background technique [0002] In recent decades, with the rapid development of terahertz radiation sources and detectors, terahertz-related technologies have attracted extensive attention. Terahertz waves are electromagnetic waves with an electromagnetic frequency between 0.1 and 10 THz, and the wave band is between microwave and far infrared. The frequency of terahertz waves is much higher than that of microwaves, which can provide sufficient bandwidth, large communication transmission capacity, and wireless transmission rates up to 10Gb / s. It is expected to become the information carrier of the next generation of high-speed wireless communications. The terahertz beam is narrow, has good directivity, and has a good ability to penetrate sand, dust and smoke. Due to its good confidentiality and ...
