Abstract
There is provided a method of estimating a bit error rate in a transport channel of a wireless communication system. The method comprises the receiving a signal from a remote transmitter of the wireless communication system via a physical channel, the signal comprising data and noise forming a plurality of soft bits. The method further comprises the counting, during a period of time, a number of erroneous bits being those soft bits which have an amplitude below −2A or above +2A with A being the average amplitude of the soft bits received. Next, the number of erroneous bits is divided by a number of total bits received during said period of time in order to obtain the bit error rate. This method provides a way to estimate the BER value without knowing the exact shape of the noise distribution. In an embodiment a selection is made between two estimation algorithms.
