JPEG and MPEG compression standards are based on block discrete cosine transform (BDCT) and, when the bit rate becomes low, visually annoying blocking artifacts appear in decompressed images and videos. In this work, we attempt to characterize and quantify the blocking artifact, and then propose an iterative method for its removal by using block classi cation and space-frequency ltering. The pr...

Hard thresholding rule is commonly adopted in feature screening procedures to screen out unimportant predictors for ultrahigh-dimensional data. However, different thresholds are required adapt contexts of problems and an appropriate magnitude usually varies from the model error distribution. With ad-hoc choice, it unclear whether all important selected or not, very likely that would include man...

The quantum paradigm presents a phenomenon known as degeneracy that can potentially improve the performance of error correcting codes. However, effects this mechanism are sometimes ignored when evaluating sparse codes and logical rate is not always correctly reported. In paper, we discuss previously existing methods to compute present an efficient coset-based method inspired by classical coding...

In many pattern recognition problems, the explanation of the made classification becomes as important as the good performance of the classifier related to its discriminating capacity. For this kind of problems we can use Consolidated Trees ́ Construction (CTC) algorithm which uses several subsamples to build a single tree. This paper presents a wide analysis of the behavior of CTC algorithm for ...

Mainly, the adaptive filters are implemented in time domain which works efficiently in most of the applications. But in many applications the impulse response becomes too large, which increases the complexity of the adaptive filter beyond a level where it can no longer be implemented efficiently in time domain. An example of where this can happen would be acoustic echo cancellation (AEC) applic...

We consider the List Viterbi Algorithm (LVA) for block decoding of a concatenated channel coding system. The inner code is either convolutional or rate compatible punctured convo-lutional (RCPC), and the outer code is a cyclic redundancy check (CRC). The block error probability is deened as the probability that the transmitted sequence is not in the list of L candidates considered by the LVA. W...

The measured rate of the tracking sensor becomes biased under some operational situation. For a highly maneuverable aircraft in 3D space, the target dynamics changes from time to time, and the Kalman filter using position measurement only can not be used effectively to reject the rate measurement bias error. To cope with this problem, we present a new algorithm which incorporate FIR-type filter...

This paper considers the deployment of intelligent reflecting surfaces (IRSs) technology for wireless multi-hop backhauling multiple basestations (BSs) connected in a mesh topology. The performance proposed architecture is evaluated terms outage and symbol error probability Rician fading channels, where closed-form expressions are derived demonstrated to be accurate several cases interest. anal...
