Taking advantage of information and communication technologies, the power industry is moving towards the next generation power grid, the smart grid. This information-based power grid is expected to change the way electricity is generated, distributed, and transmitted to the consumers by enhancing the reliability, efficiency, sustainability, and economics of the grid. However, due to the high volume...
As channel time-variation increases, orthogonality among subcarriers in an orthogonal frequency division multiplexing (OFDM) symbol can be destroyed because of the relatively long symbol period, whereupon intercarrier interference (ICI) appears, and hence an irreducible error floor occurs. It was shown recently that grouping pilot tones into a number of equally spaced clusters can yield better channel...
In this paper, a novel four symbols Finite Dimensional Modulation (4FDM) in three dimensional scheme with polarization diversity is presented that seeks to combine the advantageous features of phase shift-keying and conventional orthogonal modulation. Different from QPSK, the four symbols in 4FDM are allocated in three-dimensional Euclidean space to improve the energy efficiency. In addition, the...
