This paper presents a low-complexity two-dimensional (2D) detection strategy for shingled magnetic recording (SMR) media. The detection strategy involves the use of multi-level 2D BCJR detector along-track for inter-symbol interference (ISI) cancellation and regular BCJR detector across tracks for inter-track interference (ITI) cancellation. This is applied in a multi-track two dimensional magnetic...
A combination of single parity check-code and Two-Dimensional (2D) Bahl Cocke Jelinek Raviv (BCJR) detector is used in this paper for joint detection and decoding of 2D interference channel. This is applied to a multi-track two dimensional magnetic recording (TDMR) system. The multi-level 2D BCJR detector handled the code constraint while performing joint detection and single parity decoding. Two...
The paper presents closed-form expressions for the detection, and false alarm probabilities for spectrum sensing detection in Additive White Gaussian Noise (AWGN) based on the Multitaper Spectrum Estimation Method (MTM) using Neyman-Pearson criterion. The MTM spectrum sensing is a powerful technique in Cognitive Radio (CR) systems. It tolerates problems related to bad biasing, and large variance of...
In this paper we present a modified measure of corner detector based on Harris and Stephens work. The proposed approach is based on the first derivative Gaussian filter and the 2D ISEF filter (Infinite Symmetrical Exponential Filter) instead of the use of derivative mask and the Gaussian smoothing in the previous works. The experimental results which we present are compared with other popular corner...
