Binary sequence sets with favorable correlations from difference sets and MDS codes

We propose new families of pseudorandom binary sequences based on Hadamard difference sets and MDS codes. We obtain, for p=4k-1 prime and t an integer with 1/spl les/t/spl les/(p-1)/2, a set of p/sup t/ binary sequences of period p/sup 2/ whose peak correlation is bounded by 1+2t(p+1). The sequences are balanced, have high linear complexity, and are easily generated.
