![]() In this calculation stage 110, one or more compensation frequencies are found. The MS receives one or more signals transmitted by the BS 100. This step 100 may provide initial signal for synchronization. This may be done similarly to standard frequency synchronization in WiMAX. ![]() A BS may transmit in DL, a special signal or one or more pilot signals or a mixed signal comprised of any of the above mentioned, to a MS, and may be in a number of time frames. The method may include the following steps: 3 details a method for Doppler shift estimation and compensation.
