In a cognitive radio system dynamically adjusting its modulation scheme based on detected interference, which processing challenge most directly undermines reliable communication?

💡 Explanation

Maintaining spectral mask compliance becomes critical because dynamic modulation changes the signal bandwidth and spectral characteristics. The system must prevent out-of-band emissions, therefore, strict adherence to regulations is necessary, rather than focusing solely on resource optimization or conversion accuracy.
