Ch‐Ch‐Ch‐Ch‐Changes: The Impact of Supply Base Growth, Contraction, and Turnover on Firm Innovation
ABSTRACT Modern supply chains are experiencing more disturbances due to regulatory shifts, rising sustainability standards, emerging or declining markets, and disruption to critical inputs. Some firms react by strengthening existing supplier partnerships to resist changes, while others reconfigure relationships with suppliers to embrace changes ...

Orthogonal Frequency Division Multiplexing Modelling
This work is motivated by the need to understand the performance of Orthogonal Frequency Division Multiplexing (OFDM) and Filterbank Multicarrier (FBMC). Multicarrier techniques are widely being considered for the development of the telecommunication systems such as the Long Term Evolution (LTE) networks, 5th Generation (5G) and beyond.
