“…One disadvantage of the PTS is that it introduces additional complexity and computational overhead to the transmitter. The process of dividing the signal into sub-blocks, applying phase weighting, and combining them requires increased processing resources, which can impact system performance and implementation feasibility [ 16 ]. SLM is one of the most popular PAPR reduction techniques.…”

“…Drawback of these methods is that they provide PAPR reduction at the cost of some distortion to the OFDM signal. Some probabilistic scrambling techniques such as partial transmit sequence (PTS) technique, 13 low complexity PTS method with differential evolution algorithm, 14 selective mapping (SLM), 15 improved SLM scheme, 16 modified Class‐III SLM, 17 hybrid method using perfect sequence, 18 Trellis shaped based method 19 does not cause any signal deformation but it demands extra bandwidth overhead because of the necessity of transmitting side information (SI).…”

Cognitive radio (CR) incorporating orthogonal frequency division multiplexing (OFDM) is an intelligent spectrum sharing technique that acquires high data rate in frequency selective fading environment. OFDM has been successfully used for 4G and specific version of OFDM is being considered as the multiple access technology for 5G as well. However OFDM signal is more likely to have high peak‐to‐average power ratio (PAPR). Similarly, the sideband power of secondary or temporary users (SU) in CR can lead to interference to the licensed or primary users of the neighboring bands. In this work, an improved technique for the joint minimization of sideband power and PAPR using Zadoff‐Chu (ZC) sequence is proposed for CR based on OFDM technology. Furthermore, we propose a detection algorithm based on a binary hypothesis testing problem to recover the chosen ZC sequence at the receiver side eliminating the requirement of side information (SI) transmission. Simulation studies of the proposed method exhibits the efficiency of the concurrent reduction of PAPR and sideband power along with a huge bandwidth saving by the omission of the SI transmission.
