Interleaved cyclic redundancy check (CRC) code
The Thrity-Seventh Asilomar Conference on Signals, Systems & Computers, 2003, 2004In this paper, we investigate interleaved cyclic redundancy check (CRC) code. The interleaved CRC can be obtained by merging independent small message blocks into one large block (merged interleaving) or by dividing the original message block into independent small sub blocks (divided interleaving) and then by alternatively dividing the resulting ...

While parity checks are useful for low data rates and asynchronous messages where large gaps in between successive bytes make compilation of data into block impossible, for more general protection of data a much more robust error detection scheme is necessary.

Cyclic redundancy checks with factorable generators
IEE Proceedings - Communications, 2003Applications are proposed for cyclic redundancy checks (CRCs) that have factorable rather than primitive generator polynomials. Suitable encoding and decoding methods are developed. Factored-generator CRCs are then compared with tandem CRCs that have an inner code and outer code. When the factors of the generator are used as the generators of the inner

, 2003 A study of adaptable co-processors for Cyclic Redundancy Check on an FPGA
2012 International Conference on Field-Programmable Technology, 2012Cyclic Redundancy Check (CRC) is a well known error detection scheme used to detect corruption of digital content in digital networks and storage devices. In this paper, we present a study of different approaches of designing highly adaptable co-processors for CRC on an FPGA which are used in many network and server applications.

Analysis of checksums, extended-precision checksums, and cyclic redundancy checks
IEEE Transactions on Computers, 1990The effectiveness of extended-precision checksums is thoroughly analyzed. It is demonstrated that the extended-precision checksums most effectively exploit natural redundancy occurring in program codes. Honeywell checksums and cyclic redundancy checks are compared to extended-precision checksums.

Sphere decoder for polar codes concatenated with cyclic redundancy check
Science China Information Sciences, 2019The existing cyclic redundancy check (CRC)-aided successive cancellation list (CA-SCL) decoder partitions the decoding process into two steps,where an SCL is followed by a CRC check. An SCL decoder can approach the maximum-likelihood (ML) decoding performance of the inner polar codes using a sufficiently large list; however, in this case, CRC is only ...

Computation of cyclic redundancy checks via table look-up
Communications of the ACM, 1988Cyclic Redundancy Check (CRC) codes provide a simple yet powerful method of error detection during digital data transmission. Use of a table look-up in computing the CRC bits will efficiently implement these codes in software.

Cyclic Redundancy Check Based Data Authentication in Opportunistic Networks
2019Opportunistic Networks (OppNets) work with dynamic topology, neither having focused management nor any protection system. Security is a challenging and open research issue in OppNets. A source node always has the concerns about its data. The success of any network depends on percentage of guaranteed and authenticated delivery that it can provide from ...
