Blockchain Knowledge and Intention to Use Blockchain-Based Services
Published 2025-01-01“…The study revealed that 1) over half of the respondents rated their knowledge level as below ‘neutral’ (1 to 3 points) (253 out of 400); 2) the majority of respondents showed a low level of objective knowledge (380 out of 400 scored under 50%), especially regarding the technology’s building blocks; 3) a moderate-to-strong monotonic relationship was observed between subjective knowledge and the intention to use blockchain-based services (r<inline-formula> <tex-math notation="LaTeX">${}_{\mathrm {s}} =0.580$ </tex-math></inline-formula>); and 4) a weak-to-moderate monotonic relationship was found between objective knowledge and the intention to use blockchain-based services (r<inline-formula> <tex-math notation="LaTeX">${}_{\mathrm {s}} =0.334$ </tex-math></inline-formula>). …”

Generalized Filter Bank Orthogonal Frequency Division Multiplexing: Low-Complexity Waveform for Ultra-Wide Bandwidth and Flexible Services
Published 2024-11-01“…The main advantages are summarized as follows: (1) The <i>K</i>-point IFFT is implemented by two levels of IFFTs in smaller sizes, i.e, performing <i>M</i>-point IFFT in <i>N</i> times and performing <i>N</i>-point IFFT in <i>M</i> times, where <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>K</mi><mo>=</mo><mi>N</mi><mo>×</mo><mi>M</mi></mrow></semantics></math></inline-formula>. (2) The proposed waveform can accommodate flexible subcarrier spacings and different numbers of the subbands to provide various services in a single GFB-OFDM symbol. (3) Different bandwidths can be supported using a fixed filter since the filtering is performed on each subband. …”
