Optical Communications: 64-QAM classification with neural networks. Investigating the performance of an OFDM-based communication system with QPSK and QAM modulation and effects of AWGN and multi-path ...

Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

The distribution of content involves the need to adapt digital information to its means of carriage — what we typically call transmission — and to understand that fully, we need to understand the ...

Half the bits are represented on the real axis and half the bits are represented on the imaginary axis. The in-phase and quadrature signals are independent level Pulse Amplitude Modulation (PAM) ...

Quadrature Amplitude Modulation (QAM) has been a fundamental component in the evolution of mobile connectivity. As the demand for faster data speeds and more efficient network utilization continues to ...

Once you buy an HDTV it doesn't take long before you get confused by all the acronyms. We love us some HD, but the days of simply bringing a new set home and plugging into a coax cable are long over - ...
