abstract = {This master thesis analyses different channel estimation techniques in an OFDMA (Orthogonal Frequency Divvision Multiple Access) system with parameter settings from IEEE 802.16e and WiMAX (Worldwide Interoperability for Microwaves Access). IEEE 802.16e is one of the standards that create the foundation for WiMAX. OFDM (Orthogonal Frequency Divvision Multiplexing) is a transmission technique that is based on many orthogonal carriers that transmits simultaneously. All the channel estimators studied uses pilot symbols to estimate the radio channel. The analysis of the channel estimators has been conducted using a Matlab simulator implemented for this master thesis. The simulator evaluated the different channel estimators for different frame allocations and at different relative speeds. Two major conclusions were reached. The first is that the best method to estimate the radio channel is to estimate its taps and the second is that the choice of interpolation method affects the estimation considerably.},
