In this paper, we propose an iterative SSS detection scheme for neighbor cell search in 3GPP LTE systems. The proposed scheme contains three stages for each iteration. At the first stage, SSS is detected without channel information and a candidate cell is selected. Then a coherent detection is utilized with channel response estimated from the candidate's SSCH at the second stage, in which a corresponding...
This paper presents a novel SSS detection method for the second step of neighbor cell search in 3GPP LTE TDD systems. The proposed method is based on coherent detection and contains two stages. At the first stage, SSS is detected by using estimated channel response at PSCH. Owing to the difference of channels between PSCH and SSCH in TDD mode, the channel response estimated from PSCH does not exactly...
In LTE system, in order to access the network, user equipment (UE) should detect the primary synchronization signal (PSS) and secondary synchronization signal (SSS) in downlink (DL) signal from the surrounding base stations (BS). This paper presents a novel initial cell search (ICS) scheme in TD-LTE system that contains two steps. In the first step, modified normalization based PSS detection is proposed...
This paper presents some key issues in fiber-optic interferometric magnetic field sensors. Practically applicable methods to design and implement fiber-optic Michelson interferometer and transducers are described with experimental verifications. Detection scheme of traditional hardware demodulation is improved, and a new software demodulation method is addressed. Transducers were implemented by using...
