The authors characterize cross-correlation distributions for a family of binary m-sequence decimations with n=2k and v₂(s)>v₂(k). Noncoprime decimation yields 2ʳ+1 short-period sequences, and each has the same four possible correlation values, with frequencies determined for every offset. For s=2, k=3, the three period-21 sequences have distinct offset-class counts; this is exact characterization, not evidence of improved communications performance.
