Abstract :
This paper proposes new criteria MPRDS (Minimum Peak Running Digital Sum with Sign Change) and ABSRDS (Absolute Running Digital Sum) schemes for evaluating the quality of candidate codewords in multimode codes. The schemes have similar performance and much simpler complexity compared to MSW (Minimum Squared Weight), which is known to be the best. In addition, this paper also introduces MTO/SC (Minimum Threshold Overrun with Sign Change) and MRDS/SC (Minimum Running Digital Sum with Sign Change) criteria. The MTO/SC and MRDS/SC are the improved versions of conventional MTO and RDS, respectively.
