Multiple clock cycle real-time implementation of a system for time-frequency analysis

Multiple clock cycle implementation of a flexible system for time-frequency (TF) signal analysis is presented. It allows TF distributions (TFDs) to take different numbers of clock cycles and to share functional units within a TFD execution. These abilities represent the major advantages of multicycle design and they help reduce both hardware complexity and cost. The designed hardware is suitable for a wide range of applications, because it allows sharing in realization of some frequently used TFDs: Spectrogram (SPEC), S-method (SM) for various convolution window widths, and pseudo Wigner distribution (WD), as well as for the realization of the higher order TFDs.
