Abstract
Markov models and values of channel capacity are presented for multile vel sequences with the number of signal levels ranging from four to se ven, subject to three classes of channel-input restrictions. Several n ew line codes suitable for use in digital-communication systems are pr esented, together with their error-propagation properties and power sp ectral densities. These codes satisfy restrictions regarding runlength and zero-frequency components.
