“…4), which only use two shifters and three adders to calculate various mathematical functions, including trigonometric, division, hyperbolic, and logarithmic functions. As a result, the CORDIC algorithm has low computational complexity and consumes relatively few FPGA resources [37]. Due to this reason, the complexity of the CORDIC algorithm is neglected from the analysis.…”

“…However, the expansion area's restriction and the addition of the extension factor of this algorithm led to a decrease in peak reduction performance. Although Algorithm 4 can be classified in the group of CAF methods, which are the least computationally complex and have a simple practical 36), (37) and A ccnf by using (43). 6: Apply an IFFT to (A ace + A ccnf ) to obtain the timedomain peak-adjustment signal a.…”
