Commonly Notified Classes of Emission

The document lists examples of radio systems and their corresponding descriptions of emissions and classes of emission. It includes mobile services like GSM, UMTS, and CDMA as well as fixed services, radiolocation, radionavigation, aeronautical systems, TV and sound broadcasting. Common classes of emission include phase modulation (G7W), amplitude modulation (A1A, A3E), frequency modulation (F1B, F3E), and digital modulations like OFDM and COFDM (X7FXF, X7WXF).
