Improved decoding scheme with phase information in the wireless communication system using magnetic fields

A wireless communication system using magnetic fields is a new technology for wireless communication in harsh environments. The system utilizes current loop antennas for radiating magnetic fields on which a signal is loaded. The target application of this system is monitoring the status of buildings, bridges, underground pipes, etc. The amount of data which is required to be transferred is not huge. However, the property of target applications requires fast communication between coordinators and nodes which are facilitated in buildings and bridges. So, multiple detection at one broadcasting from a coordinator is a very crucial issue. In this paper, a multiple detection algorithm with phase differences between nodes is proposed. In addition, the proposed algorithm is evaluated by comparing the performance of the proposed algorithm with that of the traditional algorithms.
