Abstract :
This correspondence presents a theorem which allows the generation of many pseudonoise (PN) codes with known bounds on the crosscorrelation function by modulo-2 adding two maximal linear sequences (MLS) which have some given cross-correlation bounds. The application of this work can generate codes with lower predicted cross-correlation upper bounds (which is helpful in coherent correlation systems) than developed by Gold, and there is no restriction on the length of the PN register.
