Unitary Matrix Frequency Modulated OFDM for Power Line Communications over Impulsive Noise Channels
نویسندگان
چکیده
Power line channel is the time-frequency variant channel with impulsive noise. Therefore, power line communication makes performance degradation due to time-frequency variant and impulsive noise. To overcome performance degradation, we consider the unitary signal constellation scheme and investigate the performance improvement of unitary matrix frequency modulated orthogonal frequencydivision multiplexing(OFDM) for power line communication(UMFM-PLC/OFDM) over a PLC channel, and evaluate the BER performance. The proposed UMFM-PLC/OFDM system outperforms compared with the conventional PLC/OFDM.

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

Smart grid can be a solution for reducing greenhouse gas (GHG) emissions. To perform its task, smart grid needs a communication link to communicate between nodes or devices. Using power-line communications (PLC) is beneficial as the power-lines infrastructure has been available. However, in PLC the transmitted signal undergoes multipath channels and impulsive noise corruption. Meanwhile, orthog...

We discuss the decoding of error-correcting block codes over complex numbers for the transmission over impulsive noise channels. The encoder multiplies a vector of complex information symbols resulting from a modulation scheme, e.g., quadrature amplitude modulation (QAM), with a unitary generator matrix . Choosing the inverse Fourier transform as , the encoding procedure is similar to orthogona...

Orthogonal Frequency Division Multiplexing (OFDM) has become a popular modulation method in high speed wireless communications. By partitioning a wideband fading channel into flat narrowband channels, OFDM is able to mitigate the detrimental effects of multipath fading using a simple one-tap equalizer.
