Abstract :
Frequency shift keying is effective in communicating through dispersive or multipath fading channels, but it often cannot provide a sufficiently high data rate. Nonorthogonal coding can be used to obtain an increased data rate without an increased bandwidth. A reasonable increase in energy per bit is required to maintain a given error rate. Several nonorthogonal coding techniques are presented and discussed.
