SFR-v1: FM Reception Speech Dataset

Dataset Summary

SFR-v1 consists of segmented 10-second FM reception audio clips accompanied by frame-level RSSI (Received Signal Strength Indicator) traces. This dataset is designed to support research in hybrid digital-analog communication, channel-aware audio recovery, speech enhancement, and FM channel modeling. It includes multiple content types (news, music, speech, male and female voices) under varying channel quality conditions.

Audio Parameters

• Sample rate: 24 kHz
• Bit depth: 16-bit PCM
• Channels: Mono

RSSI Parameters

• Acquisition: a probe signal used solely for RSSI acquisition and not part of the audio
• Original interval: ~60 ms per measurement (with timestamp)
• Resampling: interpolated to 50 ms per step, yielding 200 RSSI values per 10-second clip
• Raw range: approximately –65 dBm to –105 dBm
• Normalization: linearly mapped to [4, 20], where higher values indicate poorer channel quality
• Alignment: RSSI sequences are frame-aligned with each audio segment
