چکیده
Signalspace Detection (SSD) is a promising concept for symbol detection, especially on magnetic recording channels. We introduce a concept of adaptive SSD, that is characterized by a high detection performance and robustness against parameter variation.

Adaptive Iterative Soft-Input Soft-Output Parallel Decision-Feedback Detectors for Asynchronous Coded DS-CDMA Systems
The optimum and many suboptimum iterative soft-input soft-output (SISO) multiuser detectors require a priori information about the multiuser system, such as the users’ transmitted signature waveforms, relative delays, as well as the channel impulse response. In this paper, we employ adaptive algorithms in the SISO multiuser detector in order to avoid the need for this a priori information. Firs...
متن کاملAdaptive Signal Detection in Auto-Regressive Interference with Gaussian Spectrum
A detector for the case of a radar target with known Doppler and unknown complex amplitude in complex Gaussian noise with unknown parameters has been derived. The detector assumes that the noise is an Auto-Regressive (AR) process with Gaussian autocorrelation function which is a suitable model for ground clutter in most scenarios involving airborne radars. The detector estimates the unknown...
متن کاملAdaptive Control Strategy for a Bilateral Tele- Surgery System Interacting with Active Soft Tissues
In this paper, the problem of control and stabilization of a bilateral tele-surgery roboticsystem in interaction with an active soft tissue is considered. To the best of the authors’ knowledge, theprevious works did not consider a realistic model for a moving soft tissue like heart tissue in beating heartsurgery. Here, a new model is proposed to indicate significant characteristics of a moving ...
متن کاملIndirect Adaptive Interval Type-2 Fuzzy PI Sliding Mode Control for a Class of Uncertain Nonlinear Systems
Controller design remains an elusive and challenging problem foruncertain nonlinear dynamics. Interval type-2 fuzzy logic systems (IT2FLS) incomparison with type-1 fuzzy logic systems claim to effectively handle systemuncertainties especially in the presence of disturbances and noises, but lack aformal mechanism to guarantee performance. In contrast, adaptive sliding modecontrol (ASMC) provides...
متن کاملSpace-time turbo equalization in frequency-selective MIMO channels
A computationally efficient space–time turbo equalization algorithm is derived for frequency-selective multiple-input–multiple-output (MIMO) channels. The algorithm is an extension of the iterative equalization algorithm by Reynolds and Wang for frequency-selective fading channels and of iterative multiuser detection for code-division multiple-access (CDMA) systems by Wang and Poor. The propose...
