Mobile communication systems. Access control Orthogonal frequency division multiplexing The world has witnessed the rapid evolution of wireless communication systems as the demand for information and entertainment is growing extremely at a rapid pace regardless of the users’ location. This trend continues to accelerate in today and the near future. Users embrace this new technological advancement and demand an efficient, reliable, and high-speed wireless communication network to satisfy their needs. One of the prominent solutions that could meet this demand is orthogonal frequency division multiplexing (OFDM) and multiple input multiple output (MIMO) technology. In addition, MIMO-OFDM is combined to promote the benefits of high-performance systems and exploitation of the multipath diversity, increasing data rates and link reliability. Despite all the advantages offered by the OFDM, it still suffers from a major problem which is the high peak-to-average power ratio (PAPR) and this problem continues to exist in MIMO-OFDM systems. The high PAPR in OFDM cause the efficiency of the high power amplifier (HPA) to decrease and increase power consumption. As a result, the high PAPR becomes a serious issue and the main barrier to the adaptation of OFDM multicarrier transmission in some wireless systems. Hence, median codeword shift (MCS) is proposed to reduce high PAPR problems in both OFDM and MIMO-OFDM systems with low computational complexity. In addition, embedded bit side information (SI) is adapted to improve the decoding reliability, which avoids bit error rate (BER) degradation at the receiver. With all the advantages possessed by the proposed MCS, a joint technique between MCS and discrete Hartley transform (DHT) is proposed to improve the PAPR reduction capability in DHT and simultaneously achieve a substantial PAPR reduction without compromising its BER performance. This research concludes with a performance comparison of the MCS and MCS-DHT with the effect of diversity schemes in MIMO-OFDM systems. In order to support the effectiveness of the proposed methods, PAPR and BER performances are analyzed to measure the percentage of improvement. From the overall experiment, the simulation results showed a significant improvement of MIMO-OFDM system performance of PAPR and BER by 33.9% and 66.7%, respectively. 2022 Thesis https://ir.uitm.edu.my/id/eprint/76533/ https://ir.uitm.edu.my/id/eprint/76533/1/76533.pdf text en public phd doctoral Universiti Teknologi MARA (UiTM) College of Engineering Idris, Azlina
