Abstract :
We derive a new expression to evaluate the low-frequency spectrum-weight (LFSW) of state-dependent encoded sequences with an arbitrarily high-order spectral at zero frequency. Based on this analysis, a selection criterion for superior suppression of low-frequency components in multimode codes with a spectral at zero frequency is proposed.
