A method and arrangement for measuring the bit error rate and / or frame error rate of a mobile telephone

摘要

For measuring the bit error rate and / or frame error rate (bler) of a mobile telephone (dut) is made of a measuring instrument (cmu) in the mobile telephone (dut) without activation of the rlc protocol - mac - a test signal is fed with a conventional data frame structure; this test signal is in the mobile telephone (dut) and then demodulated and decoded again newly coded and modulated transmitted back to the measuring instrument (cmu); in the measuring instrument (cmu), this defines signal is compared with the original test signal and, finally, the bit error rate and / or frame error rate (bler) is calculated.
