Simulation of Frequency, Timing Acquisition, and Cell Search Algorithms for OFDMA Based Mobile WiMAX

Mobile WiMAX is based on orthogonal frequency division multiple access technique. It, therefore, inherited the frequency and timing offset problems which contribute to the loss of the transmitted data. To overcome these problems, the transmitter and receiver must be well synchronized. This paper addresses the Mobile Wimax concept and introduces synchronization algorithms for frequency, timing acquisition, and cell search. These algorithms have been simulated under adaptive white Gaussian noise and fading channel for different values of signal to noise ratio. The simulation results obtained show that most of the errors have been successfully illuminated.
