Study on Oversampling Gain

摘要：

When the signal duration is fixed, whether parameter estimation precision can be improved by increasing the sampling frequency (oversampling) to get more sampling points? This problem of over-sampling gain is discussed. Over-sampling parameters estimation of complex sinusoid signal is studied in this paper, its oversampling gain is analyzed in theory, the simulation experiments are made, and simulation results are analyzed.
