Modeling and analysis of a tandem link connection under the burst-error condition

Transmission errors are known to be bursty in nature. In block-oriented data communication, this bursty error behavior should be treated assuming that there are non-renewal correlations between the transmission conditions of data block. In this paper, using the stochastic sequential machine method the authors suggest a block-level burst error model of a digital tandem connection that consists of a set of segmented channels, and then investigate several end-to-end error performance characteristics under the burst-error condition. Also, they derive expressions that approximate the tandem connection model parameters by combining individual segment channel models into an equivalent combined error model. They show the proposed method is very useful in describing the error performance of tandem link connections
