Standard Bit Error Rate (BER) Versus Received Signal Level Testing

摘要

Bit error rate (BER) bench testing of digital radios in a back-to-back mode essentially determine hardware characteristics independent of external anomalies such as impulse noise, fading, and interfering signals. This method employs the statistic of a characteristic theoretical curve of a long term BER versus received signal level (RSL). The attenuation is initially set to produce a BER of approximately .0001 at a corresponding RSL. When this point on the curve is statistically valid long term BERs can be predicted to correspond with the RSL. (Author)
