Channel Impulse Response Estimation in IEEE 802.11p via Data Fusion and MMSE Estimator

Figure 8

Packet error rates for (a) 50 and (b) 200 OFDM payload symbols frames; BPSK modulation is used, and the vehicle travels at 150 km/h. The piecewise constant line represents the selected channel update rates based on eSNR.
