Abstract :
An efficient multi-cycle signal adaptive hardware design of a system for time-frequency (TF) analysis is proposed. By taking a variable number of clock (CLK) cycles (the only necessary ones regarding the high auto-term quality) in different TF points within the execution, the proposed design allows the implemented system both to optimise execution time and to produce a pure cross-terms-free Wigner distribution (WD) signal representation.
