Abstract
Upstream (US) funneling noise suppression may be provided. First, a signal comprising a plurality of mini-slots in a two dimensional time frequency space may be received by a funneling noise suppressor. Next, the power level in each of the plurality of mini-slots may be determined. The received signal may then be outputted. Outputting the received signal may comprises outputting the received signal with mini-slots muted in the received signal that have a power level less than a predetermined threshold.
