Abstract:
1. A method for creating a filter, the method comprising: receiving a signal including a data frame, and a gap occurring before the data frame, the data frame including a data frame preamble, and the gap not including predetermined data; sampling noise received during reception of the gap of the received signal; sampling the data frame preamble of the data frame of the received signal; computing, using at least one processor, filter coefficients based on the noise sampled during reception of the gap and the data frame preamble sampled from the data frame; generating, based on the computed filter coefficients, a filter; applying, in response to generation of the filter, the filter to the data frame of the received signal; and forwarding, in response to application of the filter to the data frame of the received signal, the filtered data frame.
