Abstract
Systems, devices, and methods for mitigating collisions between wireless transmissions operating at different bandwidths are disclosed. As such, a wireless device operating at a predefined bandwidth includes a transceiver that receives a signal across a wireless channel, a filter that generates a band-limited filtered signal at the predefined bandwidth of the wireless device, a correlating mechanism that correlates the band-limited filtered signal with a delayed, conjugated version of the band-limited filtered signal, logic that performs a moving average of the correlated filtered signals to determine correlation peaks, and logic configured to compare the correlation peaks with a predetermined threshold. With this configuration, if the correlation peaks are greater than the predetermined threshold, the received signal is determined to operate at a wider bandwidth than the predefined bandwidth of the wireless device, and the wireless device defers accessing the wireless channel to transmit until a predetermined time interval.
