The invention relates to a method for estimating a channel bit error ratio in a receiver, and to a receiver. In the method, a pseudo bit error ratio of a channel is determined. The receiver ( ) comprises detecting means ( ) for detecting a data sequence of a received signal; decoding means ( ) for decoding a first encoding of the detected data signal; and re-encoding meant ( ) for re-encoding with the first encoding the data sequence decoded from the first encoding. The receiver ( ) of the invention further comprises quality determining means ( ) for providing the detected data sequence with a value for quality, and estimating means ( ) for estimating the bit error ratio-provided that the quality of the detected data sequence fulfils a predetermined quality requirement by comparing the detected data sequence with the data sequence re-encoded with first encoding. The first encoding is typically a convolution coding. One way in which quality can be determined is to decode the second encoding which is, for example, a cyclic redundancy check.
