基于OFDM窄带载波通讯技术的研究与应用
Research and Application of OFDM-based narrowband carrier communication technology
In this paper, through the OFDM error correction technology, time and frequency domain interleaving technology, research and diversity, channel equalization, channel mapping technology and a series of physical layer communication technologies, a variety of techniques to optimize a combination of careful selection and repeated applications to achieve overcoming time-varying, noise, attenuation, distortion, etc., to form a stable, robust and efficient system of power line communication channels, thereby solving some of the problems in the information collection system of the local communication channel exists; Same time, designed a method for evaluating the performance of carrier communication, and compared several common carrier solutions to verify the reasonableness and accuracy of the method.
