Abstract : Multilevel code mates A and B expanded in accordance with the expressions A = a, b sub K and B = a sub K, b are compressed to a lobeless basic mate pair by repeatedly compressing corresponding code mate pairs in successive stages to provide diminishing codes of half the code length by amplifying the code mates by a predetermined amplification factor and then adding and subtracting the code mates in accordance with the expressions A sub i-1 = A sub i + B sub i K sub i and B sub i-1 = A sub i K sub i - B sub i where i is the i sub th compression stage and K sub i is the amplification factor applied to the codes A sub i and B sub i.
