Based on assumption of perfect synchronization, a scheme defined as 4-ary Elliptical Phase Shift Keying (4-EPSK) has shown advantage over QPSK on noise performance. However, the analysis also shows that performance of 4-EPSK is vulnerable to synchronization errors. To realize efficient signal detection and simplicity of receiver, in this paper, we propose a timing recovery algorithm for 4-EPSK transmission by employing envelope characteristics of 4-EPSK signal. The proposed technique realizes estimation and recovery of time offset through self-processing envelope of the received signal. The evaluation results demonstrate that the proposed technique is effective when time offset of a received 4-EPSK signal is smaller than half symbol duration.
