摘要：Embodiments allow a wireless device configured to work with the 802.11n/acstandard to work in the communication bands where 802.11p devices operate with little
change. Embodiments may receive signals using a receiver adapted for the widerbandwidth 802.11n/ac signals. Embodiments may also increase the sensitivity of thereceiver to reduce the likelihood of missing the presence of a lower bandwidth 802.11psignal. When a signal is detected, embodiments may process the incoming signal as if itwere an 802.11n/ac signal while also processing incoming signal samples in a way thateffectively narrows the receiver bandwidth to identify whether an 802.11p signal ispresent. If the device detects the presence of an 802.11n/ac signal, it may terminate the802.11p signal processing and proceed with normal 802.11n/ac operation. If the devicedetects the presence of an 802.11p signal, it may terminate 802.11n/ac processing andtrigger collision avoidance processes.
