One alternative for improving the performance of INTELSAT's intermediate data rate (IDR) service is to use a more robust error correction coding such as the Reed-Solomon (RS) codec. The RS codec when concatenated with the existing Convolutional encoder/Viterbi decoder of IDR modems can improve the modem performance significantly. This paper presents the results of field characterization tests carried out by AT&T, in cooperation with GUATEL, during 1993. The results showed that IDR links upgraded with the RS codec perform substantially better than a conventional IDR. Furthermore, the results at C-band suggest that even at locations that exhibit high rain precipitation, an IDR with the RS codec is expected to operate at a BER lower than 10/sup -9/ for 99.96% of the year.< >
Basic decoding characteristics of a minimum bit error decoding (MBED), originally proposed by Bahl et al., is investigated. It is shown that MBED can predict the bit error rate of each decoded bit with good precision....
