Error correction enhancement with interleaves for DC free codes
Spectral shaping codes are digital codes especially designed in such a manner that their alphabets give rise to predetermined frequency spectrum envelopes. This implies that the signal energy of these alphabets will be concentrated into a predetermined range of a given frequency spectrum. The design of digital codes in the above mentioned fashion is done in order to match specific channel constraints in the design of transmission, multiplexing or storage systems. In certain applications it is desirable that spectral shaping codes provide some error correction capability or that they possess an increased robustness to errors. These errors may be introduced during transmission, processing or storage of digital information. In this paper, an interleaving method is introduced to increase the robustness of DC free codes toward burst errors whilst maintaining the spectral shaping property of DC free codes. Interleaving when applied to a coded communication system results in a reduction in the mean bit error rate (BER) of coded bit streams.
