ere is a trade-off for choosing the value of D: a higher D leads
to higher PAPR reduction but at the expense of higher complexity,
whereas a lower D gives a smaller PAPR reduction but with less com-
plexity. For example, if W = 2 and V = 4, then in C-PTS there are eight
iterations and hence P = 8D. If D = 2, then P = 16 and both methods
have the same number of iterations. But when D = 1, then the number
of iterations to find the optimum phase factor will be reduced to four
and this will result in complexity reduction. e main advantage of
this method over C-PTS is the reduction of complexity while at the
same time maintaining the same PAPR performance. In the case of
C-PTS, each row of the matrix
