A generator matrix for a linear [,,]-code has format , where n is the length of a codeword, k is the number of information bits (the dimension of C as a vector subspace), d is the minimum distance of the code, and q is size of the finite field, that is, the number of symbols in the alphabet (thus, q = 2 indicates a binary code, etc.).
Free Fire is a free-to-play battle royale game developed and published by Garena for Android and iOS. [ 4] It was released on 8 December 2017. It became the most downloaded mobile game globally in 2019 and has over 1 billion downloads on Google Play Store. In the first quarter of 2021 it was the highest grossing mobile game in the US. [ 5]
Formally, a parity check matrix H of a linear code C is a generator matrix of the dual code, C ⊥. This means that a codeword c is in C if and only if the matrix-vector product Hc ⊤ = 0 (some authors [1] would write this in an equivalent form, cH ⊤ = 0.) The rows of a parity check matrix are the coefficients of the parity check equations. [2]
The U.S. Centers for Disease Control has issued a health advisory about an alarming rise in cases of parvovirus B19. The childhood illness — also known as Fifth Disease, or “slapped cheek ...

In June, authorities in Alabama said 55 pounds of cocaine with an estimated value of $450,000 washed up on Dauphin Island in Mobile County, The Associated Press reported.
Repeat-accumulate code. In computer science, repeat-accumulate codes ( RA codes) are a low complexity class of error-correcting codes. They were devised so that their ensemble weight distributions are easy to derive. RA codes were introduced by Divsalar et al. In an RA code, an information block of length is repeated times, scrambled by an ...
