Abstract
Expanded multiplexed noise codes formed from code mate pairs of equal code length and having autocorrelation functions which upon detection provides an impulse autocorrelation function are generated by delaying one of the code mate pairs (code b) by a time delay less than its code length and adding it to the other code mate pair (code a) to form a first expanded code mate (code A) while a second expanded code mate (code B) is generated by forming the complement of the delayed code b and adding it to code a. Such partial overlapping results in expanded codes which also compress to an impulse when detected with a matched filter. These expanded codes, moreover, are utilized in multiplexed noise code modulated communications systems.
