CRC Algorithm
This algorithm allows us to transmit a data word to the receiver and, at the receiver,
check if a transmission data error occurred. I have chosen arbitrarily a data word to
transmit of 1001, The common divisor is 1011. The common divisor is used to create
the CRC check by the CRC generator.
Creating the CRC check number
The code word comprises the data to be sent 1001 plus the CRC check (the
remainder 110)
Let’s suppose were now transmit the code word 1001110. How do we check if it has
arrived at the receiver without corruption?
We must apply the CRC algorithm and if the result is 0 then the data word 1001 is
accepted.
