Hybrid System for Time-Frequency Signal Analysis

In this paper, we propose a hybrid system suitable for time-frequency (TF) signal analysis. This system applies the S-method for TF signal analysis and introduces an architecture that balances two traditional extremes. A single-clock-cycle (SCI) design delivers the fastest execution but demands prohibitively high hardware complexity, whereas a multiple-clock-cycle (MCI) design reduces hardware requirements at the cost of slower execution. The proposed solution blends the strengths of both approaches, trimming hardware complexity while keeping execution time short enough for practical use. Trade-offs and comparisons of the proposed design regarding the critical design performance and the competitive designs are also provided.
