And demodulation is practically the exact opposite, where the message signal is extracted from the carrier wave and used. In this article, we are going to learn about modulation and more about ...

The receiver conducts the reversed operation to the transmitter, and to decompose the amplitude and phase of the subcarrier to the digital signal, where the FFT transform is used. 3.2 OFDM modulation ...

Based around TurboConcept's LDPC decoder and Commsonic's adaptive APSK demodulator ... techniques for linear modulation, synchronisation and FEC, the new Standard is able to deliver at least 30% ...

Abstract: In this paper, the performance of generic orthogonal space-time block codes (OSTBCs ... expression for quadrature amplitude modulation (QAM) introduced by Cho and Yoon [9], the exact ...

Then, dual-rotation strategy, i.e., exterior and interior rotations, are utilized to introduce PB phase and chirality-assisted amplitude modulation, respectively. Hence, independent beamforming for ...
