+Each dataset consists of
+1,000 samples, produced by synthesizing single-channel base-
+band signals modulated with 5G-standard quadrature phase-
+shift keying (QPSK). The signals incorporate realistic pulse
+shaping and interference patterns to emulate characteristics
+representative of modern 5G communication systems. For
+reproducibility, fixed seed values were used during generation.
+Each sample contains 1,024 complex-valued in-phase and
+quadrature (I/Q) samples, captured at a 1 MHz sampling
+rate, corresponding to a time duration of approximately 1.024
+milliseconds. The signals were generated at baseband (0 Hz
+carrier frequency) with unit power prior to normalization.
+This approach aligns with common digital communications
+simulation practices, where operations are performed in the
+baseband domain for computational efficiency, followed by
+normalization during preprocessing for model input.
+All signals were generated using 4 samples per symbol and
+passed through a root-raised cosine pulse shaping filter with an
+excess bandwidth factor of 0.35. This configuration is standard
+in practice for producing spectrally efficient and distortion-
+minimized signals from digital data streams.
