K. Kopsa, Gerald Matz, H. Artés, Franz Hlawatsch · 2003
The bit error rate (BER) is an important measure of radio link quality in wireless communication systems. In this paper, we show how the BER of a joint detection receiver in the downlink of a UMTS/TDD system can be estimated without an active connection to a base station. We propose estimators for the instantaneous and average uncoded BER that are based on knowledge of the impulse responses and the power levels of surrounding base stations. The accuracy of our BER estimators is assessed through simulation of a UMTS/TDD network with different load factors. I.
