Higher spectrum efficiency is a target of the 5th generation (5G) mobile communications system. Massive MIMO is considered as one of important technologies for that purpose. Under the practical conditions that the number of antennas on user equipment (UE) is limited, multi-user MIMO (MU-MIMO) is a probable use scenario of Massive MIMO. Furthermore, massive connectivity is another important target,...
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...
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...
