JIT-SP Reproducibility Dataset v1.0

JIT-SP Reproducibility Dataset This dataset contains the research artifacts supporting the study "Goal-Constrained Just-in-Time State Preconditioning for Structurally Reconfigurable SDR Receivers: Robustness, Latency, and Computational Cost." The archive includes the frozen v2.4 confirmatory simulation materials, the v2.5 intermediate C++ implementation, and the v2.6 native GNU Radio/C++ receiver implementation. It also contains experimental results, calibration materials, software-testing evidence, and computational benchmarking records. Three receiver-state initialization strategies are investigated: reactive initialization (B1), frozen advance preparation (B2), and rank-two just-in-time state preconditioning (B3). The confirmatory study comprises 800 independent environment realizations across four operating scenarios and 2,400 QPSK-to-16-QAM transitions. The dataset supports the analysis of post-switch BER, EVM, CRC-confirmed packet recovery, numerical consistency, and computational overhead. It distinguishes independent receiver-level experiments from repeated-waveform software benchmarks. All experiments use synthetic baseband channels and software execution. Physical SDR hardware measurements and trained transition-predictor results are not included.
