Expanded Multilevel Noise Code Generator Employing Butting.
Abstract
Expanded multilevel noise codes are generated of a type termed 'code mates' having autocorrelation functions which, upon detection in a matched filter, provide an impulse autocorrelaton function. More particularly, expanded multilevel code mate pairs are generated by butting two multi-bit codes comprising a mate pair wherein one of the codes in each expanded mate pair comprises a code having a larger amplitude than the other code and whose position is mutually transposed in the expanded mate pairs and further wherein one of the butted codes is the complement or negative of one of the original or base code mates.
