Analysis Of The Maximum Correlation Peak Value And Rsrq In Lte Signals According To Frequency Bands And Sampling Frequencies

Attempts to organize a new positioning system with signals of opportunity (SOPs) has drawn attention as a substitute for when the global navigation satellite system (GNSS) is unavailable. Among various kinds of SOPs, long-term evolution (LTE) is considered a suitable candidate for a positioning system owing to its high transmission power compared to GNSS signals, high bandwidth, and high data rates. To distinguish LTE signals from each other and to recognize the base transceiver station that transmits each LTE signal, also known as eNodeB, cell identity (cell ID) must be determined. To organize a high-reliability positioning system, the maximum correlation peak value of reference signals and reference signal received quality (RSRQ) can be considered the criteria by which to evaluate the reliability of a determined LTE cell ID. This paper shows the analyzed results of real LTE signals acquired in commercial frequency bands and sampled. The correlation peak value and RSRQ are measured and compared at different spectral and sampling frequencies.
