Abstract
Noise codes are generated of a type termed 'code mates' having correlationunctions which, upon detection in a matched filter, provide an impulse autocorrelation function. More particularly, code mate pairs of at least two code bits each are generated and shown, for purposes of illustration, utilized in a communications system and wherein one code mate is comprised of two signal bits of first and second or opposite polarity, one bit of which has a larger amplitude than the other bit and wherein the other code mate is comprised of two signal bits of said second polarity, one bit of which has a like larger amplitude than the other bit.
