Bandpass Line Codes for q-ary Alphabets

Research output: Contribution to journal › Article › peer-review

Abstract

The Letter considers codes with higher order spectral zeros at DC for q-ary alphabets. A recurrence relation is derived for the number of codewords that exist for a given length and moment, which enables the correction of some recently published tables for q = 3 and q = 5. Some minimum distance properties are determined for first order codes and any alphabet, and again some recently published results are corrected.
