error correction code उदाहरण वाक्य

Normally the transmission BER is larger than the information BER . The information BER is affected by the strength of the forward error correction code.
Newer systems, however, usually now adopt near-optimal types of error correction codes that use the turbo decoding principle, where the decoder iterates towards the desired solution.
In coding theory, a "'balanced code "'is a binary forward error correction code for which each codeword contains an equal number of zero and one bits.
The coding used for US military ELF transmissions employed a Reed Solomon error correction code using 64 symbols, each represented by a very long pseudo-random sequence.
To compensate, the ML logical-format devotes a substantial portion of bits ( as forward-error correction coding ) to enhance robustness against media defects and signal noise.

Ciphertext expansion may be offset or increased by other processes which compress or expand the message, e . g ., data compression or error correction coding.
Please take a look at various edits and discussions at User _ talk : Eyreland, User _ talk : Nageh, Concatenated error correction codes, Error detection and correction etc.
Examples of such error correction coding types include turbo codes and LDPC codes, which perform close to the Shannon limit for the Additive White Gaussian Noise ( AWGN ) channel.
However, GCR has come to refer to the recording format of 6250 cpi tape as a whole, and later to formats which use similar RLL codes without the error correction code.
Prior to turbo codes, the best constructions were serial concatenated codes based on an outer Reed-Solomon error correction code combined with an inner Viterbi-decoded short constraint length convolutional code, also known as RSV codes.
