Abstract
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.
