Synchronization requirements for downlink coordinated multipoint joint transmission

This Master's Thesis aims to investigate the synchronization requirements for downlink Coordinated Multi-Point (CoMP) Joint Transmission in Long Term Evolution-Advanced (LTE-A) communication systems by utilizing mathematical proofs and MATLAB simulations. The purpose of the study is to enhance the signal to noise ratio of the cell edge users by using downlink Coordinated Multi-Point Joint Transmission scheme. This enables multiple base stations to transmit the same signal to the user equipment at the cell edge. The study will attempt to examine the system by using training symbols to estimate the channel for an accurate and efficient synchronization scheme. It will also attempt to derive a precise effect of time and frequency offset on the received signals. The Schmidl and Cox algorithm will be used for frame detection process at the receiver site, while the Zadoff-Chu sequence will be used as a reference signal for synchronization process.
