Spectrum Mask in IEEE802.11p

Spectrum Mask in IEEE802.11p. Authors:. Date: 2008-03-18. Abstract. We present the spectrum mask based on the FCC rule. WAVE system specification has mismatched spectrum masks. It means that PER(packet error rates) will be increased due to channel interference between adjacent channels.
