OFDM Frequency Offset Estimation Programs

I have downloaded several OFDM programs that primarily focus on frequency offset estimation. These programs have been packaged together for convenient access. One program estimates frequency offset by calculating the phase difference between signals, typically implementing cross-correlation or phase-based algorithms to detect carrier frequency deviations. Another program employs the least squares method for frequency offset estimation, using mathematical optimization to minimize the squared differences between received and expected signal patterns. A third program utilizes adaptive filters to mitigate the impact of frequency offset on signal quality, implementing LMS (Least Mean Squares) or RLS (Recursive Least Squares) algorithms to dynamically adjust filter coefficients. These programs have enabled me to gain deeper understanding and practical application of frequency offset estimation techniques in my research and experiments. Overall, this collection has provided substantial assistance in my learning and research endeavors by offering multiple implementation approaches for handling frequency synchronization challenges in OFDM systems.
