Error control coding

摘要: The basic goal in digital communications is to transport bits of information without losing too much along the way. level loss that tolerable/acceptable varies for different applications. measured terms bit error rate, or BER. An interesting application employs control coding a system with storage medium such as hard disk drive compact disc (CD). We can think channel block causes errors occur when signal passes through it. Regardless source, we describe problem follows: transmitted arrives at receiver after passing channel, received data will have some are error. designer would like incorporate ways detect and correct these errors. field covers processing techniques known coding.
