System, mobile communication unit and method for testing a receiver performance

The invention claims a system the invention claims a mobile communication unit and a used for analyzing the mobile communication unit of the receiver performance can be a method for. The system in emulator generating the information and transmitting signals the mode of information from the test equipment transmitted to the test of mobile communication unit. The transmitting signal through the one-way channel from the test equipment transmitted to the test of mobile communication unit. The transmission signals from the performance to be tested the receiver to receive and analyze. By analyzing the received transmission signal to obtain the transmission signal in the information contained. From the transmission of the input signal analysis information obtained by passing through independent return channel and return signal way from the test of mobile communication unit send back to. Testing equipment analysis and it is composed of which is used to receive return signal so as to obtain the return signal included in the information and the result with original the generated message comparing.
