Aufgabenstellung zur Studienarbeit SNIR Investigation for Decentralized Interference Cancellation in Mobile Radio Networks
نویسندگان
چکیده
In future mobile radio systems, interference cancellation is a very challenging issue. The decentralized iterative joint detection (JD) / joint transmission (JT) signal processing considering only partial channel state information (CSI) for intercell interference cancellation is a promising candidate for future time division duplex (TDD) based orthogonal frequency division multiplexing (OFDM) mobile radio networks.

Storage-Latency Trade-off in Cache-Aided Fog Radio Access Networks
A fog radio access network (F-RAN) is studied, in which KT edge nodes (ENs) connected to a cloud server via orthogonal fronthaul links, serve KR users through a wireless Gaussian interference channel. Both the ENs and the users have finite-capacity cache memories, which are filled before the user demands are revealed. While a centralized placement phase is used for the ENs, which model static b...

Abstract- Communication has become inevitably part of our day to day activities, in academic, business, banking, and other sectors. It has therefore become so important to implement good and efficient communication system. A reference point according to this research is the wireless sensor networking (WSN) system, and most important thing in communication is to be free from interference, attenu...
متن کاملMultistage Interference Cancellation for Multirate DS/CDMA on a Mobile Radio Channel
A novel hybrid interference cancellation (IC) scheme is proposed for the uplink of multirate directsequence code division multiple access (DS/CDMA) systems communicating over mobile radio channels. The hybrid IC scheme includes both non-decision directed and decision directed IC, joined together with a modified RAKE combiner for utilization of the diversity. The performance is evaluated via com...
متن کاملNon-Orthogonal Random Access in MIMO Cognitive Radio Networks: Beamforming, Power Allocation, and Opportunistic Transmission
We study secondary random access in multi-input multi-output cognitive radio networks, where a slotted ALOHA-type protocol and successive interference cancellation are used. We first introduce three types of transmit beamforming performed by secondary users, where multiple antennas are used to suppress the interference at the primary base station and/or to increase the received signal power at ...
متن کاملSuper-resolution broad null beamforming for cochannel interference cancellation in mobile radio networks
In this paper, an innovative beamforming-type approach for suppressing cochannel interference in mobile radio networks is introduced. This approach combines a super-resolution direction and power profile finding algorithm, together with a signal subspace-type broad null beamformer which can steer both sharp and controlled broad nulls in the appropriate directions. The latter property makes the ...
