Correlation values for Atheros adaptive noise immunity

[w]

Update: looking at the patent again:
http://www.freepatentsonline.com/7349503.html

Note that bb_m1thres and bb_m2thres refer to normalized,
self-correlated thresholds, bb_m2count_thr refers to the number of
self-correlation values (wherein a typical count would not exceed 31),
and bb_use_self_corr_low refers to an enabling bit value.

(but the variables are still quite confusing.)
