Signal Design For Good Correlation- For Wireless Communication- Cryptography- And Radar Download [updated] Jun 2026

For two distinct sequences ( \mathbfs_a ) and ( \mathbfs_b ), the cross-correlation measures their similarity. In CDMA communications, low cross-correlation means user ( A )’s signal appears as random noise to user ( B ).

No field demands "good correlation" more harshly than radar. A radar’s range resolution is directly determined by the autocorrelation sidelobe level. For two distinct sequences ( \mathbfs_a ) and
