Providing WiMAX broadband services via High Altitude Platforms (HAPs) is still an open research issue. One of the major problems affecting the system performance on the link level is Doppler Effect caused by the mobility of the served users. This paper investigates the Doppler effects on the bit error rate of mobile users in the downlink of the WiMax802.16m standard. The system key parameters that affect the error bit rate performance are also studied. These parameters include the channel propagation model. The Bit Error Probability (BEP) is the performance metric used to evaluate the downlink performance.
