S/N ratio determining method and apparatus for a receiver |
摘要 |
The signal-to-noise ratio of a signal having positive and negative components is determined by periodically sampling polarity values of the signal. The numbers of the sampled values of each polarity are accumulated. A quantitative measure of the relative accumulated numbers of the sampled values of each polarity is determined. A stored function of signal-to-noise ratio as a function of the quantitative measure and the number of samples is correlated with the derived quantitative measure.
