Modulation Diversity in Wideband In-Home PLC

چکیده
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 use a so-called unified modulation that can generate all of the above schemes, by which a “modulation diversity” can be provided to the PLC. In this paper we introduce this unified modulator and its functions in PLC.

Application of the OFDM Modulation to Power Line Communications
Power line communication (PLC) is one of the most attractive communication methods for in home networks. The ubiquitous power line has been utilized as a physical layer for building communication mainly because of the availability of a preinstalled infrastructure. In power line communications, multicarrier modulation is an efficient way to transmit information at a very high data rate. OFDM has...
متن کاملOutage Probability Bound and Diversity Gain for Ultra-Wideband Multiple-Access Relay Channels with Correlated Noises
In this paper, Ultra-wideband (UWB) multiple access relay channel with correlated noises at the relay and receiver is investigated. We obtain outer and inner bounds for the IEEE 802.15.3a UWB multiple access relay channel, and also, a diversity gain bound. Finally, we evaluate some results numerically and show that noise correlation coefficients play important role in determining relay position.

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...

The demanding requirements of future home networks will require a hybrid approach where multiple communication media are used in a coordinated manner. Wireless and powerline communication (PLC) are a natural combination due to their ability to provide extensive in-home coverage. In this work, we present measurement results from a recent study on wireless/PLC diversity [1] and propose an alterna...
متن کاملCompatibility of Ultra Wide Band (uwb) Radio with Power Line Communication Systems in Indoor Environment
INTRODUCTION The Ultra wideband (UWB) radio communication is known as a “carrier-free”, “baseband” or “impulse” technology. The basic concept is to transmit and receive an extremely short duration burst of pulses, typically having few tens of picoseconds in duration, with the resulting waveforms extremely broadband in frequency [1]. The UWB systems send a train of pulses with a very low duty cy...
