Sentence examples for block codes based on from inspiring English sources
In [7], delay tolerant distributed space-time block codes based on threaded algebraic space-time (TAST) codes [10] are designed for unsynchronized cooperative network.
LDPC codes are linear block codes based on a parity-check matrix called an H-matrix, in which rows and columns represent parity-check codes and symbols, respectively.
Recently, low bit-rate block coding based on image downsampling prior to block coding followed by upsampling after the decoding process is proposed to improve the compression performance for low bit-rate block coders.
In particular, quasi-cyclic root-LDPC codes, irregular repeat-accumulate root-LDPC codes and controlled doping root-LDPC codes based on progressive edge growth (PEG) techniques for block-fading channels are proposed.
Alternatively, the block-based DVC architecture in[28] allowed individual blocks to be skipped, intra or WZ coded, based on the estimated accuracy of the SI.
In contrast to traditional frame-based coding schemes, the above two methods perform WZ coding (based on, e.g., turbo code) locally on the block basis.
A coded MIMO scheme for block-fading channels that consists of a channel code and a space-time code based on SSD was proposed in [34].
First, programmers write code based on requirements.
The use of Space-Time Block Coding (STBC) based on Alamouti schemes [10] implemented in a distributed manner in OFDM-based cooperative schemes has been discussed in [11, 12], while a full-rate and full-diversity quasiorthogonal STBC scheme to be applied in virtual antenna arrays was proposed in [13].
It would therefore, from a complexity point of view, be attractive to move the estimation outside the loop, only performing it once for each code block based on the transmitted pilot symbols.
This dynamic TGOB coding architecture determines each image block to be a key block or a WZ block based on spatiotemporal image analysis, resulting in a mode switch of fine granularity in both the spatial and temporal domains.
