Theoretically the proposed demodulation scheme is not influenced by the zeros of the Bessel functions, and can keep a good performance in a wide range of modulation depth. It is compared with ...

30 ‘Non-Standard Facilities’ (NSF) features. For recorded files using low-speed demodulation, an auto-detect mode that does not rely on FSK frames is also available. This allows for fax demodulation ...

Pull requests help you collaborate on code with other people. As pull requests are created, they’ll appear here in a searchable and filterable list. To get started, you should create a pull request.

To address this issue, we propose a variable modulation SCMA (VM-SCMA) that allows users to employ codebooks with different modulation orders. To guide the VM-SCMA design, a VM matrix (VMM) that ...

The PVDMP43P6G180GF is a direct conversion quadrature modulator / demodulator designed for communication systems requiring excellent linearity with the lowest power consumption in the industry. The ...

These results support the hypothesis that neural gain modulation has the computational capacity to mediate the balance between integration and segregation in the brain. The relative simplicity of our ...
