4.1 In the workbook, prepare a graph р = f (
) for BPSK and QPSK signals (redraw from figure 2 or calculate).
4.2 Use the graph to calculate the CG, provided by error-control block (n, k) code, at a given probability p d according to table 1.
4.3 Prepare to the discussion of questions.
Table 1 – Error-control code parameters for home task calculations
| Brigade number | Error probability at the decoder output p out | Error probability at the decoder input p in | Code rate R code = k / n |
| 10–4 | 5∙10–2 | 0,5 | |
| 10–5 | 2∙10–2 | 0,6 | |
| 10–4 | 10–2 | 0,7 | |
| 10–5 | 5∙10–3 | 0,8 | |
| 10–4 | 2∙10–3 | 0,9 |
