Pipelined design of a system for highly nonstationary FM signals estimation

Pipelined signal adaptive hardware implementation of an optimal time-frequency (TF) filter has been designed. It is based on the real-time results of TF analysis and on the TF analysis-based instantaneous frequency (IF) estimation. The implemented pipelining technique allows the filter to overlap in execution unconditional steps performimg in neighboring TF instants and, therefore, to significantly enhance time performance. The improvement corresponding to the one clock cycle by a TF point is achieved, which means that the improvement by a TF point can reach even 50% in some TF points. The design is tested on multicomponent signals.).
