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. |
