Analysis of digital signal quality indicators based on analytic and stochastic modeling

This work is devoted to determination of the relationship between two different approaches for wireless link quality assessment: 1) using continuous error rate parameter of bits flow - bit error rate (BER), and 2) quality parameters defined in the ITU-T G.826 standard (12/2002) for digital paths - errored block (EB), errored second (ES), severely errored second (SES), and respective Ratio parameters (EBR, ESR, SESR). The simulation model is built for generating errors with known BER parameter and for statistical estimation of respective G.826 standard parameters. Finally, a coincidence of simulation model and analytical calculation results is demonstrated.
