Low correlation interleaved QAM sequences
Gagan Garg, P. Vijay Kumar, C. E. Veni Madhavan · 2008
Three low correlation interleaved QAM sequence families are presented here. In a CDMA setting, these sequences have the ability to transport a larger amount of data as well as enable variable-rate signaling on the reverse link. These constructions have the lowest known value of maximum correlation magnitude of any sequence family with the same alphabet.
