Investigation of data transmission over SST channel

The paper concentrates on the effect of FEC on the supplementary signal transmission (SST) channel. The SST channel and its possible applications are discussed, as its uses are unexplored in South Africa. The noise properties of the channel are investigated, with and without forward error correction (FEC). A discussion of FEC is given to introduce the concept and functional operation of the system. Bit error rates are measured without the use of FEC, to demonstrate the problem and the effect of the FEC on the noise corrupted data is presented.
