ABSTRACT:
Expanded multiplexed noise codes including code mate pairs having autocoration functions which upon detectionprovides an impulse autocorrelation function are generated by delaying the inverse of one of the code mate pairs (code b) by a value .tau. 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 delaying the inverse of said other code (code a) also by a value .tau., forming the complement thereof and adding it to said one code mate (code b). Such an expansion enables each expanded code to begin with each different code of a mate pair.
