Summer takes N samples and compares sum to
threshold Correlator multiplies R by its
expected value and compares to a threshold,
improving on the summer by giving more weight to
samples with more signal power. LLR performs
log-likelihood ratio test and compares to a
threshold, improving on the correlator by taking
into account the relationship between the samples
via the correlation matrix.
