摘要：
Undetectable errors in packets are minimized by verifying the CRC in each packet, setting a CRC flag to 0 to indicate success, and setting the CRC flag to 1 to indicate failure. If at least one packet in the set of packets fails then generate an error pattern E for each packet by comparing the packet that fails with one packet that passed the CRC verification, and comparing the error pattern to a set of known error patterns. Then, setting a CRC flag to 0 to indicate success and passing the payload of each packet and the CRC flag to the application if the difference is less than a predetermined threshold, and otherwise, setting the CRC flag to 1 to indicate failure.
