Low complexity Wizard amplitude shaping system for peak‐to‐average power ratio reduction

Performance analysis of V‐OFDM for acoustic communication along drill strings

“…Vector orthogonal frequency division multiplexing (V‐OFDM), which was first proposed by Xia to reduce the cyclic prefix (CP) and inverse fast Fourier transform (IFFT) size, can achieve a good compromise of complexity between the transmitter and receiver [14–16]. Owing to its flexibility regarding the size of the vector block, it can be adapted to meet different requirements such as the peak‐to‐average power ratio (PAPR), complexity of transmitter and receiver, and data rate [17–19]. Orthogonal frequency division multiplexing (OFDM) and single‐carrier frequency domain equalisation (SC‐FDE) are two special forms of V‐OFDM, with the former having a vector block size of and latter having a vector block size of .…”

Partial phase weighting selected mapping scheme for peak‐to‐average power ratio reduction in orthogonal frequency division multiplexing system

“…To overcome the PAPR problem of OFDM system, many PAPR reduction schemes have been proposed [3], such as clipping [4], companding [5, 6], constellation extension [7], coding [8], tone reservation and injection [9], constant envelope and constant amplitude [10, 11], partial transmit sequence [12–15] and selected mapping [16–22]. Among all the existing PAPR reduction schemes, selected mapping (SLM) is one of the most attractive schemes because of its good PAPR reduction performance without any signal distortion.…”
