Performance evaluation of hybrid ARQ schemes of 3GPP LTE OFDMA system [PDF]

, 2007
Expectations and requirements for future wireless communication systems continue to grow and evolve. Thus, recently, the Third Generation Partnership Project (3GPP) has considered the Long Term Evolution (LTE) of 3G - also known as Super 3G - to ensure ...

CRC-aided Multiple Traceback Decoding Algorithm of Spinal Code [PDF]

Jisuanji gongcheng, 2017
In order to improve the decoding efficiency of Spinal code,the beam search and Cyclic Redundancy Check(CRC)decoding are considered as a whole for joint decoding,a CRC-aided multiple traceback decoding algorithm is proposed.The correct decoding route is ...

On the Pseudocodeword Redundancy

, 2010
We define the AWGNC, BSC, and max-fractional pseudocodeword redundancy of a code as the smallest number of rows in a parity-check matrix such that the corresponding minimum pseudoweight is equal to the minimum Hamming distance. We show that most codes do

Cyclic lowest density MDS array codes [PDF]

, 2009
Three new families of lowest density maximum-distance separable (MDS) array codes are constructed, which are cyclic or quasi-cyclic. In addition to their optimal redundancy (MDS) and optimal update complexity (lowest density), the symmetry offered by the

ATF4‐mediated stress response as a therapeutic vulnerability in chordoma

Molecular Oncology, EarlyView.
We screened 5 chordoma cell lines against 100+ inhibitors of epigenetic and metabolic pathways and kinases and identified halofuginone, a tRNA synthetase inhibitor. Mechanistically halofuginone induces an integrated stress response, with eIF2alpha phosphorylation, activation of ATF4 and its target genes CHOP, ASNS, INHBE leading to cell death ...

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

Codes over Matrix Rings for Space-Time Coded Modulations

, 2010
It is known that, for transmission over quasi-static MIMO fading channels with n transmit antennas, diversity can be obtained by using an inner fully diverse space-time block code while coding gain, derived from the determinant criterion, comes from an ...

Cyclic redundancy check-aided successive cancellation-based polar decoders

Indonesian Journal of Electrical Engineering and Computer Science, 2023
<span>Research on channel coding for network transmission using polar codes has produced excellent results. By removing error redundancy from the decoding process, cyclic redundancy check (CRC) is frequently used by researchers to increase a system’s performance.
