Abstract :
The minimum squared weight (MSW) criterion has been shown to yield excellent performance for DC-free multimode codes in terms of coding efficiency. However, it is demonstrated that the MSW criterion is not sufficient to guarantee the generation of DC-free sequences. To overcome this drawback, a modified MSW criterion is proposed that integrates the MSW criterion with a word-end running digital sum constraint that ensures DC balance.
