Ranging in Wimax

The initial range is the process of estimating the distance or propagation time between a transmitter and a receiver. Area information can be used to assist in setting operating parameters for the transmitter and receiver. Since each MS has a unique distance from the base station, it is critical in the uplink to synchronize the … Read more

Terminal Transmitting and Receiving Process in Wimax

Transmitting:  The process is similar to that of BS. The frequency offset is pre-corrected. The Ranging and BW Request are generated at the physical layer and a code is selected according to the indication at the MAC layer.  After the modulation, they are mapped to competitive slots  selected at the MAC layer. Later, they are … Read more
