PROBLEM TO BE SOLVED: To provide a capability for estimating QoS watched from an end user by providing a method and a device for estimating a bit error rate in respect to a bearer service to use a convolution coding scheme. SOLUTION: In a universal mobile telecommunication system(UMTS) based system, a wireless receiver performs 'effective signal-to-noise (Eb /No ) based BER estimation'. Especially, the wireless receiver is provided with a rake receiver, a processor and a memory. The rake receiver processes a received signal and provides an S/N value in respect to each of slots in each of receiving frames of the received signal. The processor converts such an S/N value in respect to each of receiving frames to an effective S/N value in respect to the received signal. Then, the processor uses the effective S/N value as a pointer or index in respect to a look-up table (stored in the memory) and retrieves a BER estimate value therefrom.
