A combined interpolation method for waveform reconstruction in beacon transmitter detector

When beacon transmitter detector making measurements on high speed beacon signal, interpolation is required to reconstruct waveform from sampled waveform data for optimal waveform viewing. In this paper, the linear interpolation and sine interpolation are introduced and analyzed firstly. Then utilizing the characteristics of beacon transmitter detector, a combined interpolation method which consists of the linear interpolation and sine interpolation is proposed. Simulation results show that the proposed combined method has good waveform reconstruction performance and relatively low computational complexity. It is very suitable for implementation of waveform reconstruction in beacon transmitter detector.
