Question: For a TDD UE to undergo the simultaneous demodulation test with FDD transmission, what is a prerequisite regarding its receiver antenna connectors?
Option 1: At least one receiver antenna connector with correlated fading and AWGN signals.
Option 2: Exactly two receiver antenna connectors with correlated fading but uncorrelated AWGN signals.
Option 3: At least two receiver antenna connectors where the fading of the signals and the AWGN signals applied are uncorrelated.
Option 4: A minimum of three receiver antenna connectors, all with uncorrelated fading and correlated AWGN signals.
Explanation: This is correct because the test's validity hinges on the TDD UE having at least two receiver antenna connectors. Moreover, to accurately assess simultaneous demodulation capabilities without interference from correlated signal treatments, the fading of the signals and the AWGN signals applied to each connector must be uncorrelated, ensuring a realistic and unbiased test environment.
