Optimized Gateway Placement for Interference Cancellation in Transmit-Only LPWA Networks

Sensors, 2018
We study the placement of gateways in a low-power wide-area sensor network, when the gateways perform interference cancellation and when the model of the residual error of interference cancellation is proportional to the power of the packet being ...

Multiuser Massive MIMO Systems With Time-Offset Pilots and Successive Interference Cancellation

IEEE Access, 2019
This paper proposes time-offset pilots for a single-cell multiuser massive multiple-input multiple-output (MIMO) system and studies its performance under the minimum mean-squared error channel estimator and successive interference cancellation.

Multi-Feedback Interference Cancellation Algorithms for OFDM Systems over Doubly-Selective Channels

Algorithms, 2015
Orthogonal frequency-division multiplexing (OFDM) systems over rapidly time varying channels may suffer from significant inter-carrier interference (ICI), which destroys the orthogonality between subcarriers and degrades the detection performance ...

ADAPTIVE ARRAY SYSTEM FOR JAMMING SOURCES CANCELLATION IN TWO DIMENSIONAL PLANES

Journal of Engineering and Sustainable Development, 2016
The aim of this paper is to enhance the desired signal reception while suppressing the reception of inference signals to get maximum signal to interference plus noise ratio (SINR) at the output.

Multi-User Detection for Group Orthogonal Multi-Carrier Code Division Multiple Access System in Frequency Selective Rayleigh Fading Channel

Journal of Engineering and Sustainable Development, 2008
Code Division Multiple Access (CDMA) suffers from multi-user interference (MUI), and intersymbol interference (ISI) under frequency selective multi-path fading channels. Orthogonal Frequency Division Multiple access (OFDM) is MUI free but achieves lower

Intercarrier interference cancellation based on iterative detection algorithm for OFDM systems over time-varying channels

Tongxin xuebao, 2006
In order to effectically cancel the intercarrier interference（ICI） in the OFDM（orthogonal frequency-division multiplexing） systems,a novel iterative detection algorithm was proposed based on parallel interference cancellation.With the principle of ...

Research on Polarization Cancellation of Nonstationary Ionosphere Clutter in HF Radar System

International Journal of Antennas and Propagation, 2015
Oblique projection polarization filter (OPPF) can be applied as an effective approach for interference cancellation in high-frequency surface wave radar (HFSWR) and other systems. In order to suppress the nonstationary ionosphere clutter further, a novel

Blind estimation algorithm for frequency hopping parameters based on enhanced time-frequency ridge extraction

Nantong Daxue xuebao. Ziran kexue ban
In existing blind estimation algorithms for frequency-hopping parameters based on time-frequency ridges,performance degrades significantly when the signal-to-noise ratio(SNR) falls below-5 dB.
