Estimation of MIMO power line communication Channel capacity using multi-conductor transmission line theory

Though the concepts of MIMO technique is not new in the field of wireless communication, the potential of this technique is yet to be fully evaluated in the field of power line communication. In this paper one such attempt is made by comparing the Channel capacity of a MIMO power line channel with SISO power line channels of the same electrical network. To accomplish this task, a 3-wire indoor power line network is considered with multiple distributed branches. The transfer function of the power line channel is modeled using the concept of multi-conductor transmission line theory and the electromagnetic interference in the power line is modeled using the Middleton Class A noise model. To analyze the electromagnetic interference in the channel, a conducted emissions test (CE 102) is performed on the power line network.
