Communications Blockset Release Notes    

CRC Library

The Channel Coding library has been renamed the Error Correction and Detection library, and a new sublibrary, CRC, has been added to the Error Detection and Correction library. The CRC library contains new blocks for appending cylic redundancy check (CRC) bits to data and for detecting errors in transmission.

The following table lists the blocks in the CRC library.

Block Name 
Purpose 
CRC-N Generator
Generate CRC bits according to the selected CRC method and append them to input data
CRC-N Syndrome Detector
Detect errors in the input data according to the specified CRC method
General CRC Generator
Generate CRC bits according to the generator polynomial and append them to input data
General CRC Syndrome Detector
Detect errors in the input data according to the generator polynomial
