Abstract

Three typical algorithms, which are the radix-2 Fast Fourier Transformation (FFT) Algorithm, improved Discrete Fourier Transformation (DFT) algorithm, and Goertzel algorithm, are employed to decode the sub-audio signal of CTCSS. The practical consideration of implementation of the three algorithms with reasonable modification is discussed in this paper. We illustrate the decoding performance of these three approaches with experimental simulation. Finally, we summarize their technical specifications and highlight their respective advantages for the practical application.
