Advancements in Wireless Communication: Modulation, Error Correction, and Power Optimization

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.
