Phase noise compensation in Multi-carrier Wireless Communication systems

This project will open several avenues of research in the fastest growing area of telecommunications. Bandwidth-efficient data transmission over telephone and radio channels is made possible by the use of equalization to compensate for the time dispersion introduced by the channel. Quite a steady research in this field has been made in the literature for over decades. Its implementation has been mostly based on the well known mean square cost function. The traditional equalization algorithms do not take into account the transceiver impairments. One of these impairments is phase noise introduce at the transmitter and the receiver side. Phase noise is worst at the user side due to the simplicity of the algorithm to mitigate it and this is because of the limitation of the battery life. In this work, we evaluate and compare several phase noise compensation schemes that are proposed in the upcoming 3GPP long term evolution (LTE) system receivers. The tasks performed in this project will proceed in the following succession. The investigation phase will be to identify issues relevant to phase noise compensation algorithms, such as the performance and computational complexity of the algorithms. Of course different algorithms will be tested to afford the best equalization scenario. Consequently, this will result in proposing a suitable algorithm to improve performance and reduce complexity. This shall be followed by a performance evaluation phase to thoroughly investigate the proposed algorithm using analysis and simulations. The corroboration of the theoretical and simulations results will proceed thereafter. Finally, recommendations will be made and final report will be delivered.
