Title
Synchronization and Cell Searcher Design over OFDM Frame Structure Based on Millimeter Waves
Abstract
This report proposes two types of synchronization signal structure and corresponding cell searcher designs for use in orthogonal frequency division multiplexing transmission over millimeter waves. The performance of the cell searchers has been assessed in terms of detection error rate under a high-speed train environment. The simulation results provide an insight into how power spectral density (PSD) boosting is an efficient design tool to achieve both signal-to-noise ratio (SNR) gains and low implementation complexity. Accordingly, the PSD boosted design of the two proposed structures is capable of delivering SNR gains in detection probability, and low hardware complexity, at the same time. Additionally, the analysis deals with non-coherent energy combining as a useful way of improving the detection probability under various channel environments. It also revealed how trade-offs between time diversity and Doppler frequency shift under various mobility cases are tightly coupled with non-coherent energy combining.
