Effect of channel tracking using decision feedback and smoothing and of preamble and data switching. The former solves the block effect that characterized CAM PSR plots until now. The latter results in a much thicker dark red diagonal. This means that CAM dissemination from nodes to their most immediate neighbors becomes more reliable. (a) Standard IEEE 802.11 p PHY layer. (b) + decision feedback and smoothing. (c) + preamble and data switching.
