Abstract:

We investigate a new approach for designing spectral shaping block codes with a target spectrum, Ht(f), that has been specified at a plurality of frequencies. We analyze the probability density function of the spectral power density function of uncoded n-symbol bipolar codewords. We present estimates of the redundancy and the spectrum of spectral shaping codes with specified target spectral densities Ht(fi) at frequencies fi. Constructions of low-redundancy codes with suppressed low-frequency content are presented that compare favorably with conventional dc-balanced codes currently used in data transmission and data storage devices with applications in consumer electronics.
