ABSTRACT:
A method for determining the performance of decoding in a telecommunication system having a decoder and a testing apparatus for supplying test data to the decoder includes generating test data having signalling data in a signalling frame format, mapping the test data into two consecutive frames and transmitting the test data from the testing apparatus to the decoder for decoding. The signalling data is decoded from the received two test data frames and transmitted back to the testing apparatus encoded in one frame. The performance of decoding is determined by comparing the transmitted signalling data and the received signalling data in the test apparatus.
