The SAL20100E is an encoder of the turbo code specified in the 3GPP specification TS 25.212.

The basic code is an 8-state (constraint length 4) Recursive Systematic Convolutional code which is well suited to channels with predominantly Gaussian noise.

The encoder consists of two identical constituent Recursive Systematic Convolutional (RSC) coders operating in parallel on the input data frame. One RSC coder operates on the data in natural order and the other operates on a permuted version of the input data. The permutation is accomplished as described in detail in the 3GPP specification using an interleave address generator module.

The encoder outputs 3 bits for every input bit: an unencoded copy of the data, a parity bit from the first convolutional coder, and a parity bit from the second convolutional coder.
