LTE Physical Layer Identity Detection: Frequency Vs Time Domain Schemes
Long Term Evolution (LTE) physical layer identity can be recognized either in frequency domain or time domain. In this paper, the authors serve some comparisons in term of complexity, latency, and recognition probabilities in AWGN and EPA channel models. Based on their simulation, time domain scheme gives better detection performance on both channel models than the frequency domain scheme. It also fits the performance requirement in term of receiver minimum sensitivity on AWGN channel. Employing ideal frame synchronization on frequency domain detection could increase the detection performance such that exceeds time domain detection performances.
