As pointed out in the comments section of my previous blog post, Tx BER testing can only go so far in predicting the BER of a system. For rigorous Rx ...

A bit-error-rate tester can easily analyze all of these block-code-based architectures. Interleave-table dimensions and filling/draining algorithms can adapt to any of these approaches. Because ...

Bit-error-rate testers (BERTs) can generate the distinctive bathtub curve characterizing the relationship between the BER and the fraction of the UI that's available for strobing data.
