Evaluation and management coding (commonly known as E/M coding or E&M coding) is a medical coding process in support of medical billing. Practicing health care providers in the United States must use E/M coding to be reimbursed by Medicare , Medicaid programs, or private insurance for patient encounters.
The coding is done such that as long as at least k out of (k + m) chunks are available, one can recover the entire data. This means a (k, m) RS-encoded storage can tolerate up to m failures. Example: In RS (10, 4) code, which is used in Facebook for their HDFS, [16] 10 MB of user data is divided into ten 1MB blocks. Then, four additional 1 MB ...
A convolutional code that is terminated is also a 'block code' in that it encodes a block of input data, but the block size of a convolutional code is generally arbitrary, while block codes have a fixed size dictated by their algebraic characteristics. Types of termination for convolutional codes include "tail-biting" and "bit-flushing".
Pair each code word with the polarity-inverse of that code word. The receiver is designed so that either code word of the pair decodes to the same data bits. Examples include alternate mark inversion, Differential Manchester encoding, coded mark inversion and Miller encoding. differential coding each symbol relative to the previous symbol.
The distance of the concatenated code C out ∘C in is at least dD, that is, it is a [nN, kK, D'] code with D' ≥ dD. Proof: Consider two different messages m 1 ≠ m 2 ∈ B K. Let Δ denote the distance between two codewords. Then ((), ()).
Linear block codes are frequently denoted as [n, k, d] codes, where d refers to the code's minimum Hamming distance between any two code words. (The [n, k, d] notation should not be confused with the (n, M, d) notation used to denote a non-linear code of length n, size M (i.e., having M code words), and minimum Hamming distance d.)
A checksum of a message is a modular arithmetic sum of message code words of a fixed word length (e.g., byte values). The sum may be negated by means of a ones'-complement operation prior to transmission to detect unintentional all-zero messages.
The one-of-two code uses the code words 01 and 10 to encode the bits '0' and '1'. A one-of-four code can use the words 0001, 0010, 0100, 1000 in order to encode two bits 00, 01, 10, and 11. An example is dual rail encoding, and chain link [4] used in delay insensitive circuits.
