Abstract
The invention provides a channel coding method for encoding systematic data for transmission in a communication channel. The systematic data has a runlength constraint. In the method, data words are permuted. Error codes are generated based upon the permuted data words. The error codes are appended to original data words to form channel input for serial transmission in the communication channel. The number of error code bits is limited to ensure the channel input meets the runlength constraint. The error code can be a parity check bit.
