Blind Synchronization of TDMA Bursts in Non-Cooperative Environment

Blind signal identification is one of the necessities of intelligent receivers. Since burst-mode signal transmission is widely used, burst detection, i.e. detecting the beginning and the end of bursts, is an important problem. In this paper, a new method is proposed for synchronization of bursts in TDMA-based networks. The proposed iterative algorithms maps the detection result of energy-ratio detector onto the nearest TDMA structure.  In addition to Dice similarity coefficient, burst and silence errors are used to evaluate the proposed synchronization algorithm. Simulation results demonstrate the effectiveness of the proposed algorithm in improving the accuracy of burst detection. As a result, the maximum synchronization accuracy is attainable for signal to noise ratios more than -2dB.
