ii The use of Rate Compatible Punctured Convolutional codes (RCPC-codes) for rate matching in multichannel systems is also presented. A DS-CDMA system is used for evaluating purposes. The RCPC-codes are shown to provide a flexible and efficient coding scheme which is superior compared to repetition

It is supposed that there is a multichannel sensor system which performs sequential detection of a target. Sequential detection is done by implementing a generalized Wald's sequential probability ratio test, which is based on the maximum-likelihood ratio statistic and allows one to fix

are anticipated in future cellular communication systems. As a consequence, the link performance and hence the capacity of these systems will to a large extent be limited by the robustness against interference provided by the receiving terminals operating within the systems. Thus, in all future system aiming

A new, small biomagnetic system with 8 channels operating at 77 K has been constructed. In the gantry inside the magnetically shielded room it can be shifted to five positions so that up to 40 positions can be measured successively. We employ low noise dc-SQUID magnetometers from high

-gap maximization and power minimization does not hold with peak-power limitation. Based on a defined dissimilarity measure, bit-loading solutions are compared over power line communication channel for multicarrier systems. Simulation results confirm the asymptotic convergence of both allocation policies. In non

We presenf a texture segmentation algorithm inspired by the multi-channel filtering theory for visual information processing in the early stages of human visual system. The channels are characterized by a bank of Gabor filters that nearly uniformly covers the spatial-frequency domain. We propose a

A very fast FFT-based deconvolution method, which combines the well-known principles of least squares optimisation and regularisation, can be used for inverting systems comprising any number of inputs and outputs. The method was developed for the purpose of designing digital filters for multi-channel

Blind channel equalization has recently been a very active research topic due to its potential application in mobile communications and digital TV systems. In this paper, we present a new blind zero-forcing equalizer that utilizes second order statistics from the multi-channel configuration

Abstract – The basic aim of this paper is to provide an insight about various nonlinear effects that have to be taken into consideration while deploying high-bit-rate multiwavelength systems such as the WDM (Wavelength Division Multiplexing) systems.
