In this paper we discuss the application of Tomlinson-Harashima-type precoding to point-to-multipoint transmission scenarios. These include the CDMA downlink from a central transmitter (base station) to distributed, decentralized receivers (mobile terminals), as well as transmission from a satellite to multiple receiving earth stations. At the expense of only a very moderate increase in signal ...

In this paper we investigate the application of CDMA in optical communication networks. Optical fiber based communication systems has advantage of having access to large bandwidth and ultra–high speed signal processing are possible. Optical code division multiple access (O-CDMA) is evolving into a promising candidate for access networks, due to its potential for enhanced information security, s...

Acoustic signal extraction and identiication in the underwater environment is best achieved by adaptive methods as the signals encountered are generally non-stationary and corrupted by unpredictable noise sources, such as man-made noise, biological and seismic noises. While classical methods often fail in such an environment, the recent use of mul-tiresolution methods like the adaptive wavelet ...

With progress in radar systems, a number of methods have been developed for signal processing and detection in radars. A number of modern radar signal processing methods use time-frequency transforms, especially the wavelet transform (WT) which is a well-known linear transform. The interference canceling is one of the most important applications of the wavelet transform. In Ad-hoc detection met...

The use of efficient signal processing tools (SPTs) to extract proper indices for the fault detection in induction motors (IMs) is the essential part of any fault recognition procedure. The 2nd part of this two-part paper is, in turn, divided into two parts. Part two covers the signal processing techniques which can be applied to non-stationary conditions. In this paper, all utilized SPTs for n...

Propagation of radio occultation (RO) signals through the lower troposphere results in high phase acceleration and low signal to noise ratio signal. The excess Doppler estimation accuracy in lower troposphere is very important in receiving RO signals which can be estimated by sliding window spectral analysis. To do this, various frequency estimation methods such as MUSIC and ESPRIT can be adopt...

Decentralized optimization has attracted much research interest for resource-limited networked multi-agent systems in recent years. Decentralized consensus optimization, which is one of the decentralized optimization problems of great practical importance, minimizes an objective function that is the sum of the terms from individual agents over a set of variables on which all the agents should r...
