چکیده
A new Multiple-Input Single-Output Powerline Communications (MISO PLC) transmission scheme is proposed as an extension to the conventional Single-Input Single-Output (SISO) PLC transmission scheme to achieve high data rate with diversity. This scheme is called Enhanced-PLC scheme (EPLC). A Space-Time (ST) coding is employed at the transmitter terminal. In addition, a modified Maximum-Likelihood (ML) decoder is proposed at the receiver over a quasi-static flat fading channel. The derivations of Signal-toNoise Ratio (SNR), Symbol Error Rate (SER), outage probability, and spectral efficiency are conducted for the proposed PLC transmission scheme and compared to the conventional SISO and the 2X1 MISO ST-coded PLC schemes. The analytical results show that the proposed MISO PLC transmission scheme outperforms the SISO and the 2X1 MISO schemes in terms of error rate, outage probability, and rate performances.

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...
متن کاملSecurity Issues of Power Line Multi-Home Networks for Seamless Data Transmission
This paper provides discussion of security issues for power line networks (PLC). The home network based on power line communication has been used widely however security of PLC has not been discussed sufficiently. Though PLC uses power line as medium it has similar characterises with wireless communications in the view of security. The authentication and cryptographic scheme used in PLC standar...

متن کاملA Suitable Coding Scheme for Broadband Power-line Communication
This paper introduces three coding strategies for using the Luby Transform (LT) code in a relay aided power-line communication scheme. In the first method, the relay decodes the received packets and re-encodes them for transmission towards the destination. In the second method, the relay only forwardes a random linear combination of its received packets towards the destination, while in the thi...
متن کاملModulation Diversity in Wideband In-Home PLC
Abstract The power line channel is characterized by a multi-path behavior. A direct consequence is that Multi-Carrier Modulation (MCM) is generally retained for Power Line Communication (PLC). In addition to OFDM, or equivalently DMT, Wavelet OFDM and OFDM/OQAM have been recently proposed for PLC transmission. In fact, every scheme has its own pros and cons. The most effective way for PLC is to...
