A BCH code with = is called a narrow-sense BCH code.; A BCH code with = is called primitive.; The generator polynomial () of a BCH code has coefficients from (). In general, a cyclic code over () with () as the generator polynomial is called a BCH code over ().
Bitcoin Cash trades on digital currency exchanges using the Bitcoin Cash name and the BCH currency code for the cryptocurrency. [ 50 ] [ 51 ] [ 52 ] On 26 March 2018, OKEx removed all Bitcoin Cash trading pairs except for BCH/BTC, BCH/ ETH and BCH/ USDT due to "inadequate liquidity". [ 24 ]
There are many types of block codes; Reed–Solomon coding is noteworthy for its widespread use in compact discs, DVDs, and hard disk drives. Other examples of classical block codes include Golay, BCH, Multidimensional parity, and Hamming codes. Hamming ECC is commonly used to correct NAND flash memory errors. [6]
BCH code (Bose–Chaudhuri–Hocquenghem code), a code in coding theory; Bachelor of Surgery, a component of some undergraduate medical degrees; Baker–Campbell–Hausdorff formula, in mathematics and Lie group theory; Biosafety Clearing-House, an international mechanism that exchanges information about the movement of genetically modified ...
It is used as one of the steps in decoding BCH codes and Reed–Solomon codes (a subclass of BCH codes). George David Forney Jr. developed the algorithm. [1]
Chapter 5 studies cyclic codes and Chapter 6 studies a special case of cyclic codes, the quadratic residue codes. Chapter 7 returns to BCH codes. [1] [6] After these discussions of specific codes, the next chapter concerns enumerator polynomials, including the MacWilliams identities, Pless's own power moment identities, and the Gleason ...
This dress code prohibits shorts, sportswear and "overly revealing clothing," and business class passengers should be dressed "smart casual." Certain airlines have dress codes for their customers.
A certain family of BCH codes have a particularly useful property, which is that treated as linear operators, their dual operators turns their input into an -wise independent source. That is, the set of vectors from the input vector space are mapped to an ℓ {\displaystyle \ell } -wise independent source.
