Crc layer
WebIn the first step of the physical-layer processing, a CRC is calculated for and appended to each transport block. The CRC allows for receiver-side detection of errors in the decoded transport block and can, for example, be used by the hybrid-ARQ protocol as a trigger for requesting retransmissions. http://www.tcpipguide.com/free/t_DataLinkLayerLayer2.htm

WebThe Cyclic Redundancy Check (CRC) evaluation happens after FEC decode and correction. Since FEC can correct errors, it has to know the exact location and magnitude of error, in order to perform correction. Therefore, its detection ability is limited.
