Performance Analysis of Power Line Channel Using Digital Modulation Techniques

Power Line Communication has been considered as a good candidate for “the last mile” solution and for home networking. However Power line is worse than other wired transmission medium due to its noise. This paper introduces power line channel modelling and to realize reliable data communication over PLC. This paper carries the first Power line Channel properties and noise behaviour. This paper ...

Numerical Techniques Based on Radial Basis Functions

Radial basis functions are tools for reconstruction of mul-tivariate functions from scattered data. This includes, for instance, reconstruction of surfaces from large sets of measurements, and solving partial diierential equations by collocation. The resulting very large linear N N systems require eecient techniques for their solution, preferably of O(N) or O(N log N) computational complexity. ...

Speech/Nonspeech Detection Using Minimal Walsh Basis Functions

This paper presents a new method to detect speech/nonspeech components of a given noisy signal. Employing the combination of binaryWalsh basis functions and an analysis-synthesis scheme, the original noisy speech signal is modified first. From themodified signals, the speech components are distinguished from the nonspeech components by using a simple decision scheme. Minimal number of Walsh bas...
