Abstract :
A new class of pseudonoise sequences over GF(p), based on Gordon-Mills-Welch (GMW) sequences, is constructed. The sequences have the property that, in a specified zone, the out-of-phase autocorrelation and cross-correlation values are all equal to -1. Such sequences with low correlation zone (LCZ) are suitable for approximately synchronized CDMA system
