“…Secondly, if there are many wrongly predicted erasures in one RS packet, the number of errors which can be corrected in this packet will be reduced. Therefore, the concept depth of prediction (DoP) is introduced [6]. If a new error is detected and corrected in one RS packet, there are maximum DoP erasures related to this error which can be predicted in the following RS packets.…”

In this paper, we introduce a new scheme to improve the performance of the Reed-Solomon codes, which exploits the properties of the Reed-Solomon (RS) decoder to correct more errors by predicting as many erasures as possible in each RS packet in advance before decoding in the RS decoder. The concept Depth of Prediction (DoP) used for predicting erasures is introduced and derived. Simulation results show that with optimal DoP values, the new scheme yields performance gain of around 1dB at BER of 10 -8 resulting in the extended coverage area of the communication system.

“…Since the T-DMB system was based on the DAB system, it includes extra functional blocks which compose of the MPEG-4 format to MPEG-2 format converter and the forward error correction (FEC) blocks to achieve better bit error rate (BER) performance [1] [2] [3]. With the FEC blocks which consist of the Reed-Solomon (RS) encoder/decoder and convolutional interleaver/deinterleaver, we can obtain a BER rate below    for video service [4]. In order to achieve this lower error rate, we propose two types of turbo coded T-DMB system models as shown in Fig.…”

The DAB system was designed to provide CD quality audio and data services for fixed, portable and mobile applications with the required BER below   . However for the T-DMB system with the video service of MPEG-4 stream, BER should go down    by adding FEC blocks which consist of the Reed-Solomon (RS) encoder/decoder and convolutional interleaver/deinterleaver. In this paper we propose two types of turbo coded T-DMB system without altering the puncturing procedure and puncturing vectors defined in the standard T-DMB system for compatibility. One(Type 1) can replace the existing RS code, convolutional interleaver and RCPC code by a turbo code and the other one (Type 2) can substitute the existing RCPC code by a turbo code. Simulation results show that two new turbo coded systems are able to yield considerable performance gain after just 2 iterations. Type 2 system is better than type 1 but the amount of performance improvement is small.
