Waveform design is a research area focused on optimizing and designing waveforms used in various applications such as communication systems, radar systems, and signal processing. The goal is to design waveforms that are efficient, robust, and tailored to the specific requirements of the application, such as minimizing interference, maximizing signal-to-noise ratio, or enhancing target detection. Waveform design can involve techniques such as pulse shaping, modulation, code design, and optimization algorithms to achieve desired performance metrics. This research area is crucial for improving the performance and efficiency of various systems that rely on waveforms for communication and signal processing.
