Abstract :
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.
