• Cyclic packing
• impulse radio sequence
• optical orthogonal code
• ultra-wideband radio

Impulse radio sequences (IRSs) were first introduced by Chu and Colbourn in (IEEE Trans. Inf. Theory, Vol. 50, pp. 2402-2407,2004). In this correspondence, we investigate the upper bound for this class of sequences. By using the relationship between IRSs and Cps, a new upper bound for (m, k, 1) -IRS is given, which improves the Johnson bound.
