Superior execution time hardware implementation of Wiener time-frequency filter

Multiple-clock-cycle and signal adaptive, but also completely pipelined hardware implementation of the optimal (Wiener) time-frequency filter is developed and verified. The implementation retains all desirable characteristics of the corresponding recently proposed signal adaptive solution with the optimized time and hardware requirements, but additionally improves the execution time — for a clock cycle per each time-frequency point performed within the estimation, resulting in the significant improvement of up to 50% in terms of points lying outside the instantaneous frequency of the estimated signal.
