As such, each input message bit is encoded twice, which results in a code rate of 1/3. Turbo codes for pulse position modulation: applying BCJR algorithm on PPM signals Here's one way it can work: With odd parity, the 0s and 1s in the 8 bits plus the parity bit will always have...
For systematic codes, this orthogonality condition, GHT = 0, is fulfilled when the H matrix is such that upon multiplication with the code, it selects the parity bit pj from the parity part of the code and those systematic bits which constituted pj, from the systematic part of the received...

bit error and it is the easiest method for detecting errors. There are different types of error detection codes used to detect the errors they are parity, ring counter, block parity code, Hamming code, biquinary, etc. The brief explanation about parity bit, paritygeneratorand checker are ...

One bit parity encoding converts a 2N space into a 2N+1 space. Here, half the codewords are ‘valid’ and the other half are ‘invalid’. It so happens that this simple encoding operation results in a very symmetrical geometrical lattice where the minimum hamming distance between any two ...
