Fundamental frequency estimation based on mean values

Frequency estimation is an important subject of research in different research areas, such as wireless communication, acoustic and speech processing, sonar and radar measurements. Currently there are available methods that use time domain and frequency domain analysis to detect the frequency of a signal. Within this paper a new time domain method is presented, which analyses the mean values of data segments of the investigated signal. The algorithm doesn't require complex operations and gives good results with only two periods of the investigated signal.
