Real world source coding algorithms usually leave a certain amount of redundancy within the coded bit stream. Shannon (1948) already mentioned that this redundancy can be exploited at the receiver side to achieve a higher robustness against channel e

Time synchronization is required in mobile terminals operating in any digital radio system to detect the radio frame start of the received signal. The main operation performed in the synchronization procedure is the correlation between the received s

The coded data stream of today's powerful source codecs still contains residual redundancy. Due to the fact that coding is usually done frame by frame, this redundancy remains both inside a frame and also in a time correlation of successive frames. T

Two-dimensional, systematic and parallel concatenated convolutional codes are compatibly punctured in order to provide unequal error protection (UEP). They are iteratively decoded by the MAP algorithm and other soft-in/soft-out decoders. In a case st

The current maximum user data rate in GSM is 9.6 kbit/s per time slot. To increase the rate to 14.4 kbit/s by puncturing the code bits which are generated by the same convolutional coding scheme used for GSM 12.0 kbit/s, may result in a loss of about

There is often residual redundancy remaining in coded speech data, even if a powerful speech codec (e.g. the full rate coder used in GSM mobile communications) is employed. By using such redundancy together with the information provided by the channe

When transmitting speech signals, there is residual redundancy in the signal after source coding, due to the limited complexity of the coding algorithms and delay constraints. This redundancy is expressed in correlations inside one frame as well as i

In mobile speech communication usually vector quantization (VQ) is employed to ensure high coding efficiency. Convolutional coding and softbit speech decoding can add a considerable amount of robustness. VQ as well as softbit decoding however can be
