On the Feasibility of SISO /MIMO-PLC based on the Discrete Cosine Transform Type-III even

Abstract

During the last decades, power line communications (PLC) has emerged as an alternative to other wired line and wireless technologies. In particular, PLC has gained large acceptance for in-home scenarios, where it has become a competitive alternative to WiFi. Most PLC approaches are based on Multicarrier Modulation (MCM) using the Discrete Fourier Transform (DFT) as the basis to construct the multiple orthogonal channels. In this work, we explore the construction of MCM-PLC schemes based on the Discrete Cosine Transform Type-III even (DCT3e). We consider both SISO (single input single output) and MIMO (Multiple Input Multiple Output) PLC schemes, showing that they are a feasible alternative for in-home PLC applications.
