A different approach to correlation function estimation: the IPFM-based correlation
Bedini L., Giunta G., Reggianini R.This paper presents an unconventional approach to estimation of correlation functions. The approach uses a particular information-coding technique, namely Integrative Pulse Frequency Modulation, which permits to compute correlation in a very efficient way. Simulation results have shown a good performance of the method especially at low signal-to-noise ratios, in comparison with conventional techniques.Source: International Conference on Digital Signal Processing -87, pp. 149–153, Firenze, Italy, 07-10/09/1987
