Wireless transceivers for mass-market applications must be cost effective. We may achieve
this goal by deploying non-ideal low-cost radio frequency (RF) analog components …

A highly integrated fundamentally operated direct-conversion quadrature (IQ) TX/RX chipset
with a tunable carrier of 215–240 GHz for high-speed wireless communication is presented …

This paper analyzes the joint effects of in-phase and quadrature (I/Q) imbalance and power
amplifier (PA) distortion for RF multiple input multiple output (MIMO) transmitters in the …

Generalized frequency division multiplexing (GFDM) has become one of the most important
waveform candidates for air interface in 5G communications. However, like the standard …

It is well known that low-cost RF front-end implementation such as direct conversion
transmitter suffers from serious in-phase/quadrature phase (IQ) imbalance. Most existing …

Differential space time block coding (STBC) achieves full spatial diversity and avoids
channel estimation overhead. Over highly frequency-selective channels, STBC is integrated …

As known, receivers with in-phase and quadrature-phase (I/Q) down conversion, especially
direct-conversion architectures' always suffer from I/Q imbalance. I/Q imbalance is caused by …

The authors incorporate Alamouti space‐time block coded orthogonal frequency division
multiplexing (OFDM) with signal space diversity (SSD) in order to significantly strengthen the …

Digital video broadcasting terrestrial (DVB-T) systems use hierarchical modulation, which
involve a “high-priority” and a “low-priority”(LP) bit stream. An inherent weakness of this …

In this paper, we focus on improving the accuracy of frequency offset estimation for an
orthogonal frequency-division multiplexing (OFDM) system under the conditions of the joint …
