Power spectral density of a novel adaptive multilevel line code
The adaptive multilevel code (AMC) is a DC-free line code with four levels and two lengths. Both levels and lengths carry information. For a stationary memoryless source, closed-form expressions for the spectra of the AMC coded signals have been obtained analytically using the transition probability matrix method. Results comparing the one-sided spectral densities of the AMC, alternate mark inversion, and biphase waveforms are presented. The advantages of AMC are demonstrated.<>
