Description
Summary:Completely pipelined signal adaptive multicycle hardware design of the optimal time-frequency (TF) filter is developed and verified. The design retains all desirable characteristics of the corresponding recently proposed signal adaptive solution with the optimised time and hardware requirements, but additionally improves the execution time – for a clock cycle per each TF point performed within the estimation, resulting in the improvement of up to 50% in terms of points lying outside the instantaneous frequency of the estimated signal.
