Immediate treatment of heat stroke is body cooling; currently the preferred method of cooling is evaporation cooling by spraying the patient with cold water or covering them with cold water soaked sheets, and using fans to augment evaporative cooling.
Orthogonal Frequency Division Multiplexing or OFDM is a modulation format that is being used for many of the latest wireless and telecommunications standards. OFDM has been adopted in the Wi-Fi arena where the standards like 802.11a, 802.11n, 802.11ac and more.
One way in which this may. be achieved is to precede the OFDM data with a special. synchronization symbol. Two synchronization symbols are proposed. to achieve frame synchronization for an OFDM, the wobbulation. symbol and the Barker code.
