Question: In 3GPP-compliant testing for MBMS (Multimedia Broadcast Multicast Service) enhanced performance requirements type 1 with UE (User Equipment) receiver diversity, what is the specified relationship between the fading profiles used in the six faders and the two AWGN (Additive White Gaussian Noise) signals?
Option 1: The fading profiles are correlated to each other but not to the AWGN signals.
Option 2: Both the fading profiles and AWGN signals are partially correlated to facilitate realistic interference scenarios.
Option 3: The fading profiles used in the six faders and the two AWGN signals are all uncorrelated to each other.
Option 4: The fading profiles are uncorrelated to each other but must be correlated to the AWGN signals for accuracy.
Explanation: To accurately test MBMS enhanced performance with UE receiver diversity, ensuring that both the fading profiles (simulating varying channel conditions) and the AWGN signals (representing random noise) are uncorrelated to each other is crucial. This setup provides a comprehensive and unbiased assessment of the UE's ability to handle diverse signal degradation scenarios without any predetermined pattern or relationship between the signal distortions, thus closely mimicking real-world conditions.
