Abstract-- As a promising radio access technology for future 5G network, novel multiple access (NMA) is aimed to improve spectrum efficiency and access capability via design of successive interference cancellation (SIC) amenable pattern in single domain (e.g. power domain, code domain, and space domain) or joint multiple domains. In this paper, a pattern in joint space and power domain is designed...
In this paper, we introduce an improved relative channel reciprocity calibration method in TDD massive multiple-input multiple-output (MIMO) systems. The improved calibration method divide the massive MIMO system into one Single-Input Single-Output (SISO) system and two Single-Input Multiple-Output (SIMO) systems instead of calibrating the massive MIMO directly. We select the channel with high channel...
China had footnoted the frequency band will be authorized for IMT service in the 2007 World Radio Communication Conference(WRC[1]) According to China and international service applications, There will be coexistence between digital terrestrial multimedia broadcasting (DTMB) service and IMT service including TD-LTE service system. This paper targets deriving frequency isolation(FI)and appropriate coexistence...
Distributed antenna system (DAS) could provide high throughput for multi-users. The uplink sum transmission rate is studied in a multi-user DAS scenario. An uncomplicated antenna selection strategy is proposed to approach high sum rate. Considering fairness, the performance of inferior user could be improved remarkable with low sum rate loss in two-user scenario.
