Decoupled Access in HetNets With Backhaul Constrained Small Base Stations
IEEE Access, 2018 This paper investigates the uplink (UL) and downlink decoupled access in heterogeneous networks with backhaul constraints. A capacity-based user association policy is proposed for users with decoupled access, where small base stations (SBSs) connect to ...

Sub-Stream Fairness and Numerical Correctness in MIMO Interference Channels
, 2013 Signal-to-interference plus noise ratio (SINR) and rate fairness in a system are substantial quality-of-service (QoS) metrics. The acclaimed SINR maximization (max-SINR) algorithm does not achieve fairness between user's streams, i.e., sub-stream ...

Uplink Linear Receivers for Multi-cell Multiuser MIMO with Pilot Contamination: Large System Analysis [PDF]
, 2014 Base stations with a large number of transmit antennas have the potential to serve a large number of users at high rates. However, the receiver processing in the uplink relies on channel estimates which are known to suffer from pilot interference.

SINR- and MI-Based Double-Robust Waveform Design
Entropy, 2022 Owing to cognitive radar breaking the open-loop receiving–transmitting mode of traditional radar, adaptive waveform design for cognitive radar has become a central issue in radar system research. In this paper, the method of radar transmitted waveform design in the presence of clutter is studied.

Discrete Pseudo-SINR-Balancing Nonlinear Recurrent System [PDF]
Discrete Dynamics in Nature and Society, 2013 Being inspired by the Hopfield neural networks (Hopfield (1982) and Hopfield and Tank (1985)) and the nonlinear sigmoid power control algorithm for cellular radio systems in Uykan and Koivo (2004), in this paper, we present a novel discrete recurrent nonlinear system and extend the results in Uykan (2009), which are for autonomous linear systems, to ...

SINR for DS-CDMA with random spreading [PDF]
IEE Proceedings - Communications, 2005 For wireless multipath fading channels, the performance of a direct-sequence code-division multiple-access (DS-CDMA) system is degraded by interference, including multipath interference (MPI) and multiuser interference (MUI). For the downlink DS-CDMA with random spreading, we derive the variances of MPI and MUI and obtain the signal-to-interference ...

Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems
International Journal of Satellite Communications and Networking, Volume 44, Issue 3, Page 275-287, May/June 2026.ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.

Taxonomy of IMT Interference on Aeronautical Systems
Radio Science, Volume 61, Issue 4, April 2026.Abstract The rapid deployment of 5G and future 6G networks has raised concerns about interference with critical aeronautical systems, particularly radio altimeters and Wireless Avionics Intra‐Communications (WAIC). This paper offers a comprehensive taxonomy of the 5G/6G signal interference mechanisms, operational impacts, and mitigation strategies in ...
