Methods, systems, and apparatus for subcarrier modulation with radio frequency inphase-quadrature (IQ) modulators. A system includes a plurality of IQ modulators, each configured to receive an input electrical signal comprising an inphase signal and a quadrature signal, and each configured to ...
Modern digital communication systems use quadrature modulation (IQ) such as QAM. An imbalance between the I and Q paths in the RF module results in self-interference that affects both channel estimation and data demodulation. We propose unbiased training sequences that automatically eliminate the inte...
To understand how to avoid manipulating the phase of an RF carrier directly, refer to the following I/Q modulation equations: Essentially, what this fact means is that you can control the amplitude, frequency, and phase of a modulating carrier sine wave by simply manipulating the amplitudes of...

Recently, automatic modulation classification techniques using convolutional neural networks on raw IQ samples have been investigated and show promise when compared to more traditional likelihood-based or feature-based techniques. While likelihood-based and feature-based techniques are effective, making classif...
applications.In this pap-er,an IQ quadrature modulation circuit based on DDS is proposed.A two-channel DDS device is used to g-enerate two-way IQ baseband signals which would output to the quadrature modulator,directly.In the quad-rature modulator,the IQ baseband signal is modulated to RF ...
We designed a novel pilot pattern that is used by two proposed estimation and compensation methods of IQ impairments to the signal. Proposed methods were shown to significantly improve the system performance. 展开 关键词: OFDM modulation distortion frequency division multiple access signal detection ...
