The intense use of the 2.4 GHz ISM band by several wireless technologies has resulted in increased co-channel interference between networks operating in this frequency band. The aim of this paper is to investigate modeling techniques of co-channel interference affecting bluetooth low energy devices. The models are derived from recorded interference. Two types of models are introduced: a time domain model utilizing IQ data as reference and a spectrum-based model in which the reference signal is captured in frequency domain by a real-time spectrum analyzer. The recorded interference is also used as a reference to analyze the accuracy of proposed models. The proposed IQ-based model shows a degradation in performance for the environments with dominant bluetooth interfering signals. The frequency-based model not only addresses this problem, but also results in a huge data decimation in recording the interference.

多种无线技术对 2.4 GHz ISM 频段的大量使用导致在该频段运行的网络之间的同信道干扰增加。本文的目的是研究影响蓝牙低功耗设备的同信道干扰建模技术。这些模型来自记录的干扰。介绍了两种类型的模型：使用 IQ 数据作为参考的时域模型和基于频谱的模型，其中参考信号由实时频谱分析仪在频域中捕获。记录的干扰也用作分析所提出模型准确性的参考。建议的基于 IQ 的模型显示了在具有主要蓝牙干扰信号的环境中性能下降。基于频率的模型不仅解决了这个问题，
