Abstract—In slow frequency hopping systems, it is critical to detect, classify, and mitigate interference, as it degrades the system performance. Generalized likelihood ratio test algorithm was proposed for the detection of interference. Howeve

these peak-reducing signals are built by using spreading codes that are either dynamically selected those users that are known to be idle, or deliberately reserved a priorifor PAPR reduction purposes. The concept of adding orthogonal signals for peak
