Performance evaluation of source-matched blockwise decoded convolutional codes for mobile communications

In this paper the applicability of source-sensitivity matched unequal error protection schemes is studied for variable-rate speech transmission on a radio mobile channel. The performance of the unequal error protection scheme is evaluated through simulation taking into account the effects of the channel memory. The simulation of the useful signal and of the interferers is based on a fading model developed by Clarke. The effects of channel memory on different error correction schemes are evaluated and compared.
