A pseudo-pilot scheme is proposed for 802.11a and 802.11R/A (roadside applications version) in DSRC (dedicated short range communication) applications. The scheme overcomes the shortcomings of the original IEEE 802.11a standard by substituting pilots in selected data slots for channel equalization; at the receiver, the pilots are removed and random data inserted. It is shown that the technique is very effective in addressing the high mobility DSRC environment with minor changes to the 802.11a and R/A physical layer.
