A 'Nonoverlapping Block' refers to a segment of data in which each block is encoded and decoded separately without any overlap with adjacent blocks. The block length is chosen to balance compression performance, storage space, and computational requirements in applications such as signal processing. ...
Block-overlap decorrelation methods for transform coding of image signals are discussed theoretically. Methods which require the least computing time are considered, including transformation with overlapping time windows and fast convolution transformation. In an examination of system algorithms it is found ...
Recently, we proposed a time-domain block signal detection using maximum likelihood detection (MLD) employing QR decomposition and M-algorithm (TD-QRM-MLBD) for the single carrier (SC) block transmissions and showed that it can significantly improve the bit error rate (BER) performance compared ...
Overlap Save Method In this method, the size of the input data blocks is N=L+M-1 and the DFTs and the IDFTs are of length L. Each Data Block consists of the last M-1 data points of the previous block followed by L new data points to form a data sequence of length N=L+M-1...
Synchronizer is a signal-processing block (based on phase-lock-loop techniques) to ensure compensation waveforms (IAPF and/or VAPF) are correctly synchronized with the power system voltage. From: Power Quality in Power Systems and Electrical Machines (Second Edition), 2015 ...
An audio encoder/decoder uses a combination of an overlap windowing transform and block transform that have reversible implementations to provide a reversible, integer-integer form of a lapped transform. The reversible lapped transform permits both lossy and lossless transform domain coding of an audio...

This paper describes the general conditions for perfect signal reconstruction in adaptive blocksize MDCT. MDCT, or modified Discrete Cosine Transform, is a method in which blocks are laid to overlap each other. Because of block overlapping, some consideration must be paid to reconstructing the signa...
The block-based approach splits an image into blocks of square or circle for analysis during the pre-processing stage. These blocks can either overlap or not overlap with each other. Then, the features are extracted from these blocks and compared against each other to determine the similarity ...
A block transform is a technique used in image and speech coding that involves dividing an image or speech signal into sub-images and independently coding each sub-image. However, at low bit rates, this technique can result in a "blocking" effect with discontinuities at the boundaries of the...
