Technology‐Enabled Cross‐Border Entrepreneurship: The Role of Digital Platforms in SME Expansion Through the Lens of Institutional Theory

Thunderbird International Business Review, EarlyView.
ABSTRACT Small and medium‐sized enterprises (SMEs) face significant institutional barriers when expanding across borders, including regulatory constraints, financial accessibility issues, and market entry challenges. Institutional theory provides a useful framework for understanding how external regulative, normative, and cognitive institutional forces

Alteration of X‐Ray Emission Band Spectrum Under Bragg Diffraction

X-Ray Spectrometry, EarlyView.
ABSTRACT We use a Zr/Si multilayer presenting a gradient of period to probe the shape of the Si L2,3 emission band (maximum around 92 eV) in and out of Bragg conditions. The sample was prepared by magnetron sputtering and its reflectance measured in the photon energy range of interest with synchrotron radiation.

Successive Interference Cancellation in Heterogeneous Networks [PDF]

IEEE Transactions on Communications, 2014
At present, operators address the explosive growth of mobile data demand by densification of the cellular network so as to reduce the transmitter-receiver distance and to achieve higher spectral efficiency. Due to such network densification and the intense proliferation of wireless devices, modern wireless networks are interference-limited, which ...

Successive cancellation for cyclic interference channels

2008 IEEE Information Theory Workshop, 2008
The Chong-Motani-Garg inner bound for the two-user interference channel is generalized to a special case of many-user interference channels. By taking a geometric viewpoint and using rate-splitting arguments, it is shown that all operating points in the Chong-Motani-Garg inner bound allow decoding by successive cancellation at all receivers.

Successive interference cancellation

Proceedings of the 9th ACM SIGCOMM Workshop on Hot Topics in Networks, 2010
Successive interference cancellation (SIC) is a physical layer capability that allows a receiver to decode packets that arrive simultaneously. While the technique is well known in communications literature, emerging software radios are making practical experimentation feasible. This motivates us to study the extent of throughput gains possible with SIC

Power control for successive interference cancellation with imperfect cancellation

2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003
This paper proposes and analyzes an iterative power control scheme for use with successive interference cancellation (SIC) in the presence of cancellation errors. SIC is shown by Andrews and Meng (see IEEE Transactions On Wireless Communications, Oct.

A successive interference cancellation scheme for an ODFM system

ICC '98. 1998 IEEE International Conference on Communications. Conference Record. Affiliated with SUPERCOMM'98 (Cat. No.98CH36220), 2002
We consider an orthogonal frequency division multiplexing (OFDM) system with successive interference cancellation to reduce interchannel interference. The system operates in a Rayleigh frequency selective channel and pilot symbols are inserted in each OFDM frame for the purpose of channel estimation.

Mitigating Error Propagation in Successive Interference Cancellation

IEICE Transactions on Communications, 2006
In this letter, we propose a novel signal detection method for spatially multiplexed multiple input multiple output (MIMO) systems, based on the idea of ordered successive interference cancellation (OSIC). In the proposed method, we try every possible value as the first detected symbol instead of making a decision. Although the proposed method requires

Projected Kaczmarz successive interference cancellation detection

Transactions on Emerging Telecommunications Technologies, 2021
AbstractIn this article, the recently developed Kaczmarz successive interference cancellation (KSIC) detector is generalized to the nonlinear case; specifically, a projected SIC detection scheme is developed using the projected Kaczmarz iterative method.
