Abstract
A process and apparatus are disclosed for encoding input signals for transmission by a transmitter. A pattern of binary values is generated which has a predetermined average binary weight. The input signals are modulated with the predetermined pattern of binary values. The modulated signals are encoded with a forward error correction code which provides a predetermined level of coding protection. The average binary weight of the predetermined pattern of binary values is selected to be at least as great as the level of coding protection provided by the forward error correction code.
