Efficient non-coherent PSS detections and analysis for LTE systems

This works extends our previous work on cell ID detection for OFDM systems to LTE systems. Specifically, we apply our previously proposed three channel-effect resilient cell ID detection (CERCD) methods to the detection of primary synchronization signals (PSS) in 3GPP LTE systems. Simulation results show that CERCD methods still maintains merits of low complexity and high performance for LTE systems, as in IEEE 802.16e systems. Specifically, the proposed schemes have much lower complexities and significantly higher performances than the popular differential autocorrelation schemes. This is particularly beneficial for LTE system, because PSS are complex signal with high computational complexity.
