Abstract
A transmitting device generates a data block including a first field having a first plurality of bits that includes an error detection portion and a second field having a second plurality of bits; selects an error injection mask based on the second plurality of bits; modifies the first plurality of bits with the error injection mask to generate a modified first plurality of bits; and transmits the data block to a receiving device. The receiving device decodes the second plurality of bits to generate decoding results; selects an error injection mask based on the decoding results; modifies the first plurality of bits using the error injection mask to generate a modified first plurality of bits that includes a resultant error detection value indicated in the error detection portion; and detects whether the decoding results for the second field are correct based on the resultant error detection value.
