Description

The Baseband Fading Simulator ¸ABFS is suitable for universal  mobile radio applications in research, development and production. It comprises all scenarios and statistical models for simulating sporadic  fading as specifi ed in the test regulations of mobile radio standards (e.g. GSM, 3GPP WCDMA or CDMA2000®). The fl exible concept of the ¸ABFS allows the simulation of radio channels of existing and future communications systems (e.g. mobile radio, broadcasting, fl ight telephone, WLL, or WLAN systems). The ¸ABFS can also  simulate frequency hopping systems. The ¸ABFS is fast enough to follow the frequency hopping of a test system, for example within a frame of 4.616 ms (GSM frame time). Furthermore, an offset voltage for each I and Q input or output can be entered to compensate for external DC offset voltages. Together with a baseband source (e.g. the I/Q Modulation Generator ¸AMIQ,), receiver tests can be performed at the I/Q level even if the corresponding RF link is not available. During the development of receivers or correction circuits in the receiver (e.g. equalizer), the effects of fading can thus be checked at a very early stage. The ¸CMU 200 with the option ¸CMU-B17 in combination with the Fading Simulator ¸ABFS can also be used for receiver tests under fading conditions.
