Abstract : Multilevel code mates A and B expanded in accordance with the expression A = (a)I (b to the Kth power) and B = (a to the Kth power)I (b-Bar) 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 number of code bits by amplifying the code mates by a predetermined amplification factor and then adding and subtracting the code mates in accordance with expressions A(i-1) = A(i) + B(i)K(i)th power and B(i-1) = A(i) to the K(i)th power - B(i) where i is the ith compression stage and K(i) is the amplification factor applied to the codes A(i) and B(i).
