What is the formula of code rate?

The code rate is R = k/n. The Hamming distance d between two codewords is the number of positions by which they differ. For example, the codewords 110101 and 111001 have a distance of d = 2. If valid codewords are always at least a distance d = 2 apart, then it is always possible to detect a single error.

What is meant by code rate?

In telecommunication and information theory, the code rate (or information rate) of a forward error correction code is the proportion of the data-stream that is useful (non-redundant). That is, if the code rate is for every k bits of useful information, the coder generates a total of n bits of data, of which.

What is code rate in LTE?

In fact coding rate range is 0.0762 - 0.9258. Radio link quality is estimated based on CQI (Channel Quality Indicator). CQI is reported by UE (User Equipment) and measured based on Cell Reference Signal (CRS).

What is code rate in ITC?

The code rate (or information rate) is a fractional number that expresses what part of the redundant message is actually meaningful. For instance an encoder with 1/3 rate will output 3 bits of message for each bit of data. Therefore, bigger code rates produce stronger codes.
