Currently, there is an increasing demand for high-speed internet access with reliable performance. Mobile WiMAX, IEEE 802.16m is 4G technology employed for broadband internet applications. It incorporates cyclic prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) as a modulation as well as multiplexing technique. In the high-speed scenario, OFDM experiences intercarrier interference, increasing the number of bits in error. In this paper, we provide the performance assessment of Mobile WiMAX for different vehicular speed upto 350km/h. Simulation is carried out for different values of doppler frequencies upto 1200Hz and bit error rate is computed. Result reveals that Bit Error Rate (BER) performance of mobile WiMAX degrades with an increase in vehicular speed. 16QAM gives satisfactory performance in a high-speed environment upto 250km/h.
