Abstract :
A new family of binary sequences is constructed by Legendre sequence with period P, P = 3 (mod 4). The new signal set includes two subsets consisting of (P - 1)/2 and (P + 1)/2 codes with good balance property. A conjecture about the maximum over all (nontrivial) autocorrelation and crosscorrelation values of sequence contained within the two subsets is proposed
