The ASTE‐BGC Data‐Assimilative Regional Ocean Biogeochemical Model
Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.Abstract We present a data‐assimilative regional ocean biogeochemical model, ASTE‐BGC, which simulates the physical and biogeochemical state of the North Atlantic Ocean from 2002 to 2017. Model physics are provided by a physical state estimate (ASTE), which assimilates O(109) in situ and satellite‐based observations over the model domain and time ...

Efficient Helicopter-Satellite Communication Scheme Based on Check-Hybrid LDPC Coding
Tsinghua Science and Technology, 2018 When implementing helicopter-satellite communications, periodical interruption of the received signal is a challenging problem because the communication antenna is intermittently blocked by the rotating blades of the helicopter.

Construction Method of QC-LDPC Codes with Big Girth for Fast Encoding [PDF]
Jisuanji gongcheng, 2018 The sub-matrices on both diagonals of the right half of the check matrix are unit matrices.Existence of the deterministic unit matrix not only destroys the randomness of Quasie Cyclic-Low Density Parity Check(QC-LDPC) code,it leads to a certain loss of ...

, 2014 The McEliece cryptosystem is the oldest code-based cryptosystem and itis believed to resist to quantum attacks. The system was proposed in1978 by Robert McEliece. It uses irreducible binary Goppa codes, butit can be instantiated with any family of linear codes for which anefficient decoder is available.

QC-LDPC Codes Construction by Concatenating of Circulant Matrices as Block-Columns
International Journal of Information and Communication Technology Research, 2016 In this paper a new low complexity method for constructing binary quasi-cyclic low-density parity-check (QC-LDPC) codes is introduced. In the proposed method, each block-column of the parity check matrix H is made by a circulant matrix in a way that the ...
