A method of determining a channel response of a communications channel. A computing device receives a data packet via the communications channel and generates a first channel estimation based on a first portion of a preamble of the received data packet. The computing device further generates a second channel estimation based on a second portion of the preamble and determines the channel response of the communications channel based, at least in part, on an average of the first and second channel estimations. For example, the first portion of the preamble may correspond with a Long Training Field (LTF), and the second portion of the preamble may correspond with a Very High Throughput Signal B (VHT-SIG-B) field.
