Characterization and modeling of the channel and noise for broadband indoor Power Line Communication (PLC) networks.
Power Line Communication (PLC) is an interesting approach in establishing last mile broadband access especially in rural areas. PLC provides an already existing medium for broadband internet connectivity as well as ...
Effect of amplifier non-linearity on the performance of CDMA communication systems in a Rayleigh fading environment
The effect of amplifier non-linearity on the performance of a CDMA communications system
Wavelet based image compression integrating error protection via arithmetic coding with forbidden symbol and map metric sequential decoding with ARQ retransmission
The phenomenal growth of digital multimedia applications has forced the communications
Repeat-punctured turbo trellis-coded modulation.
Ever since the proposal of turbo code in 1993, there has been extensive research carried out to improve both the performance and spectrum efficiency. One of the methods used to improve the spectrum efficiency was to ...
Packet scheduling in satellite LTE networks employing MIMO technology.
Rapid growth in the number of mobile users and ongoing demand for different types of telecommunication services from mobile networks, have driven the need for new technologies that provide high data rates and satisfy their ...
An improved randomization of a multi-blocking jpeg based steganographic system.
Steganography is classified as the art of hiding information. In a digital context, this refers to our ability to hide secret messages within innocent digital cover data. The digital domain offers many opportunities for ...
Cross-layer design for multimedia applications in cognitive radio networks.
The exponential growth in wireless services and the current trend of development in wireless communication technologies have resulted into an overcrowded radio spectrum band in such a way that it can no longer meet the ...
Modelling of propagation path loss using adaptive hybrid artificial neural network approach for outdoor environments.
Prediction of signal power loss between transmitter and receiver with minimal error is an important issue in telecommunication network planning and optimization process. Some of the basic available conventional models in ...
A flexible statistical framework for the characterization and modelling of noise in powerline communication channels.
One communication medium that has received a lot of interest in recent years is the power line channel, especially for the delivery of broadband content. This channel has been traditionally used to carry electrical power ...
