Determination of the bit error rate in a European DAB receiver

摘要

A performance measuring apparatus (700) is provided to a channel decoding apparatus for use in a European digital audio broadcasting (DAB) receiver. The performance measuring apparatus includes a puncturing information inserting unit (710) that inserts an information data as puncturing information in the signal inputted to the Viterbi decoder (600) of the channel decoding apparatus, and an error calculating unit (750) that calculates a decoding error rate of the Viterbi decoder by comparing the input to the Viterbi decoder and the re-encoded output (740) from the Viterbi decoder.
