Abstract
This note corrects a recurrent erratum in Section VII of our paper “An MTL-based channel model for indoor broadband mimo power line communications” [1] . Errors are concerned with the quantification of the spatial correlation of MIMO channels by means of the condition number of the channel matrix. According to the definition given in expression (25) of the paper, the higher the condition number, the higher the spatial correlation. However, Section VII is written as if high condition numbers correspond to low spatially correlated channels. Hence, whenever it is said that a given fact reduces the spatial correlation or, equivalently, that it yields lower spatially correlated channels , it should say exactly the opposite, i.e, the referred fact increases the spatial correlation or yields higher spatially correlated channels; and vice versa.
