![]() The simulation shows that, with this scheme, smaller numbers of sampling points are needed to generate one histogram, so the estimation of the Q‐factor is much simpler and faster. The calculated results are independent of the difference between the data rate and sampling rate. We can also obtain a higher linear relationship between Qavg and the real Q‐factor than conventional approaches can. With this method, a low distortion histogram can be obtained and the convergency of the averaged Q‐factor (Qavg) with respect to the number of sampling points can be significantly enhanced.
