<p> Precise frequency and phase estimation are important aspects of a telecommunication system. They are the important sub-system of communication, navigation, radar, and various other engineering systems. Systems and methods provide fast and precise frequency estimation by keeping minimal sampling and a high tolerance to noise. Methods used to estimate the frequency include multiple phase shift keying and multiple quadrature amplitude modulation scheme. This project utilizes a frequency estimation technique to keep sampling minimal and to have a high endurance to noise for better performance. Recently, fast and precise frequency estimation have become increasingly important in the evolution of the Orthogonal Frequency Division Multiplexing. Previous techniques of frequency estimation are based on the Extended Kalman Filter and Fast Fourier Transform. This project has developed a fast and precise carrier frequency estimation scheme. The Kalman Filter approach, Classen approach, and Moose approach are used for the carrier frequency estimation.</p>
