Abstract: Union modulation scheme is proposed and analyzed based on trellis-coded modulation, orbital angular momentum (OAM), and quadrature amplitude modulation (QAM). Specifically, source data ...

The non-orthogonal multiple access (NOMA) scheme has been recognized as a promising candidate for future generation wireless communication networks that require a high data rate and spectral ...

Brief introduction to high-speed, interface basics, as well as the industry motivations driving demand for 200 Gigabits per second (Gbps) connectivity. Review of the challenges faced with scaling ...

Abstract: We present two multilevel constant-envelope continuous-phase modulation (CPM) schemes with four-dimensional (4-D) trellis coding. The receiver is composed of a simple quadrature demodulator, ...
