Abstract :
This letter presents three methods that can transform ternary complementary sequence sets (CSSs) into 8-QAM+ CSSs. Method 1 yields 8-QAM+ CSSs with sequences of even length. Method 2 works for sequences with an arbitrary period, but results in 8-QAM+ CSSs with a size twice that of the ternary sets. Method 3 transforms ternary CSSs with odd periods into 8-QAM+ CSSs, but with double the period. The resultant 8-QAM+ CSSs can be applied to signal processing, channel estimation, and synchronization.
