New Beamforming and Relay Selection for Two-Way Decode-and-Forward Relay Networks

Multiple access broadcasting (MABC) is a spectral efficient protocol in two-way relay channel (TWRC). The drawback of this protocol in decode-and-forward (DF) mode is decoding complexity at the relay side. Erroneous decoding at the relay can lead to error propagation…

Argo: A Real-Time Network-on-Chip Architecture With an Efficient GALS Implementation

In this paper, we present an area-efficient, globally asynchronous, locally synchronous network-on-chip (NoC) architecture for a hard real-time multiprocessor platform. The NoC implements message-passing communication between processor cores. It uses statically scheduled time-division multiplexing (TDM) to control the communication over a…

Shaping physical machine topology in distributed data center networks

Physical machines (PMs) constitute the hardware infrastructure in data centers. Proper distribution and placement of PMs plays an important role in determining the system performance. Existing PM placement approaches generally ignore the demands of virtual machines (VMs), resulting in a…

Initial synchronization assisted from inherent diversity on LTE sector search process

Estimations of time error and frequency offset upon initial synchronization are investigated in this paper as components of the sector search process in third-generation partnership project (3GPP) long-term evolution (LTE) communications. The proposed system considers intercell interference, inter-carrier interference and…
