Building compact and low-cost yet flexible and reconfigurable radios for future wireless
systems is generally a challenging task. On one hand, the needs for flexibility and re …

Accurate channel estimates are needed in orthogonal frequency-division multiplexing
(OFDM), and easily obtained under the assumption of perfect phase and frequency …

The radio frequency (RF) impairments of analog devices have been regarded as an
important factor degrading the performance of Terahertz (THz) communications, where in …

In this paper, we present a duplexing method for wireless communication that allows both
transmission and reception to occur at the same frequency band and time slot …

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 …

Orthogonal frequency division multiplexing (OFDM) is a popular modulation technique for
wireless digital communications. It provides a relatively straightforward way to accommodate …

We develop robust mean-square error (MSE)-optimal training signal designs for multiple-
