“…Although determining suitable codes and offsets requires a lot of work, it provides the benefits of power control and mistake correction. Additional approaches [9], [8] include employing Complementary Block Coding (CBC) to reduce the PAPR without reducing the frame size. As shown in [10], a pool of candidates is produced using Reed-Solomon (RS) codes over the Galois field, and the best candidate is picked from this pool.…”

OFDM systems outperform single-carrier systems in a multiple-path fading channel. Optical frequency division multiplexing (OFDM) systems are widely utilized in today's high-speed wired and wireless networks, such as those used for digital television broadcasting (DVB), IEEE 802.11 and IEEE 802.16, HIPERLAN Type II, digital subscriber lines (DSL), home networking, etc. There is much enthusiasm for using OFDM systems in 4G wireless networks. The current rise in interest in OFDM may be attributed to the technology's promise to provide high data rate transmission under frequency selective fading settings when Inter symbol Interference (ISI) is prevalent. Taking use of the advantages of multi-path fading's diversity requires appropriate frequency interleaving and coding. There has been a lot of research on finding the optimum techniques for both encoding and decoding data to facilitate transmission by means of OFDM under fading circumstances, since coding is an essential part of most OFDM systems.
