Patent ID: 8526939

Claim:
A method for testing a mobile-radio device with a tester, wherein payload data are transmitted between tester and mobile-radio device via a multi-antenna system, in which a transmitted signal, composed of a plurality of modulated carrier signals with different carrier frequencies, is transmitted, with the following method steps: allocating the data to be transmitted to a plurality of carrier frequencies and coding parameters for each transmission antenna; generating a plurality of modulated carrier signals corresponding to the allocated carrier frequencies and coding parameters; distorting one or more modulated carrier signals of a plurality of modulated carrier signals by means of a frequency-selective, static channel model in the frequency domain; transmitting a transmission signal, which is composed of the channel-modeled, modulated carrier signals, to a mobile-radio device in the time domain; determining information regarding carrier frequencies and coding parameters of the received signal in the mobile-radio device and transmission of the determined information to the tester, wherein in the tester, the information regarding the carrier frequencies received in the mobile-radio device and the coding parameters of the individual modulated carrier signals, which the mobile-radio device determines, is evaluated with the original allocation information, which was allocated to the data to be transmitted during the allocation for each transmission antenna in the tester, and the information regarding the static channel model used; and wherein the allocation of the data to be transmitted to a plurality of carrier frequencies and coding parameters for each transmission antenna for the next data to be communicated is implemented on the basis of the information evaluated in the tester regarding the carrier frequencies and coding parameters received and determined in the mobile-radio device and reported back to the tester.
