Iraq RF Spectrum Dataset: Real-World Multi-Band Raw IQ Measurements from Baghdad – Part5

Part 5 of the Iraq RF Spectrum Dataset: Real-World Multi-Band Raw IQ Measurements from Baghdad, Iraq. This record contains raw IQ measurements corresponding to Day11 through Day20 of the measurement campaign. Day11 is distributed across four ZIP archives (Day11-1 to Day11-4) solely for storage and transfer purposes; these archives collectively represent the Day11 recordings and do not constitute separate measurement days. The measurements were acquired in Baghdad, Iraq, using an RTL-SDR V3 receiver and GNU Radio with an Osmocom Source under real-world indoor and outdoor RF conditions. The acquisition settings used a sample rate of 2.048 MS/s, with fixed receiver gains of RF = 40 dB, IF = 30 dB, and BB = 20 dB. The recordings cover multiple RF bands and center frequencies, including FM, VHF, UHF, 433.92 MHz ISM, 868/915 MHz ISM/LoRa, GSM900, and 1090 MHz ADS-B. Raw complex IQ samples are provided for reuse in spectrum sensing, spectrum occupancy analysis, cognitive radio, dynamic spectrum access, wireless communications, and machine-learning-based RF research. The accompanying Iraq_RF_Master_Metadata_FINAL.csv provides recording-level metadata for the complete multi-part dataset (Day1–Day20; 295 raw IQ recordings), including recording date, estimated start time where available, recording duration, session, indoor/outdoor environment, elevation context, center frequency, frequency band, sampling rate, receiver gain settings, and timing provenance. Recording times documented as estimated were derived from preserved file timestamps together with recording duration and should not be interpreted as independently measured acquisition timestamps. No external RF calibration instrument or calibrated reference signal was used during the measurement campaign. Post-acquisition quality control was performed on the stored IQ data and is distinct from RF calibration. This dataset is distributed across multiple Zenodo records because of its large total storage size. The division into ZIP archives and Zenodo parts is for data storage and transfer only and does not alter the underlying raw IQ measurements.
