An Extension Method to Construct M-Ary Sequences of Period 4N with Low Autocorrelation

An Extension Method to Construct M-Ary Sequences of Period 4N with Low Autocorrelation

Pseudorandom sequences with low autocorrelation magnitude play important roles in various environments. Let N be a prime with N=Mf+1, where M and f are positive integers. A new method to construct M-sequences of period 4N is given. We show that these new sequences have low autocorrelation magnitude.
