• Impulse radio sequence
• optical orthogonal code (OOC)
• optimal
• strictly cyclic packing

Impulse radio sequences were first introduced by Chu and Colbourn in 2004. A better upper bound for (m, k, 1)-IRS was given by Gao and Chang in 2006. In this paper, we present an upper bound for (m, k, lambda)-IRS with lambda >= 2, which improves the known Johnson bound.
