The recent developments in the field of wireless communication and signal processing have been marked by significant advancements in modulation techniques, error correction, and power optimization strategies. A notable trend is the focus on enhancing the efficiency and performance of Orthogonal Time Frequency Space (OTFS) and Orthogonal Frequency Division Multiplexing (OFDM) systems, particularly in reducing peak-to-average power ratio (PAPR) and optimizing power amplifier (PA) performance. Innovations in decoding algorithms for convolutional and turbo codes have also been prominent, with efforts directed towards achieving near-optimal performance with reduced computational complexity. These advancements are crucial for the development of next-generation wireless systems, including 5G and IoT applications, where energy efficiency and signal quality are paramount.
