Improved Successive Interference Cancellation for MIMO/UWB-Based Wireless Body Area Network

open access: yesInternational Journal of Antennas and Propagation, 2012
In body area networks, various sensors are attached to clothing or on the body or even implanted under the skin. The sensors measure such as heart beat, the record of prolonged electrocardiogram, blood pressure, and so on.

Optimal Power Allocation Scheme Based on Multi-Factor Control in Indoor NOMA-VLC Systems

open access: yesIEEE Access, 2019
In order to overcome the limitation of narrow modulation bandwidth on the performance in the visible light communication (VLC) systems, non-orthogonal multiple access (NOMA) is applied to the downlink VLC networks in this paper to improve the sum rate ...

Successive interference cancellation schemes for time-reversal space-time block codes [PDF]

open access: yes, 2008
In this paper, we propose two simple signal detectors that are based on successive interference cancellation (SIC) for time-reversal space-time block codes to combat intersymbol interference in frequency-selective fading environments. The main idea is to

Successive Interference Cancellation Decoding With Adaptable Decision Regions for NOMA Schemes

open access: yesIEEE Access, 2022
In this work, we propose adaptable decision regions in the successive interference cancellation (SIC) decoder for the three-user uplink/downlink non-orthogonal multiple access (NOMA) scheme by exploiting the knowledge of the channel gains.

Uplink Non-Orthogonal Multiple Access (NOMA) Decoding Based on Successive Parzen Windows Interference Cancellation

open access: yesIEEE Open Journal of Vehicular Technology
In this paper, a novel decoding kernel method based on Successive Parzen Windows Interference Cancellation (SPWIC) is proposed for the Non-Orthogonal Multiple Access (NOMA) uplink. The procedure leverages on the diversity in both angle and received power
