Abstract: A versatile sequence set design with both low cubic metric (CM) and low maximum-absolute-crosscorrelation is proposed for pilot-less sequence-based transmission as a solution to current pilot/symbol-based 5G design in coverage-limited scenarios. Based on generalized second-order… read more here.
