In this paper, we propose the use of the "longitudinal resonance condition" for the characterization of the two-dimensional propagation of surface acoustic waves (SAWs) in periodic grating structures, and also show a procedure for extracting param...

In this paper, we propose a physical model for the analysis of transverse modes in surface acoustic wave (SAW) devices. It is mostly equivalent to the scalar potential (SP) theory, but sufficiently flexible to include various effects such as aniso...

A direct-conversion receiver (DCR) can reduce the power consumption and cost. However, a DCR with orthogonal frequency-division multiplex (OFDM) suffers from IQ imbalance. Until this time, many algorithms have been proposed to compensate IQ imbala...

This paper discusses the measurement setup of non-linearity caused in radio frequency (RF) surface and bulk acoustic wave (SAW/BAW) devices with high signal-to-noise ratio (SNR). It is shown that when some important points are considered, the back...
The symbol timing synchronization inaccuracy can bring about phase offset (FO), inter-symbol interference (ISI) and inter-channel interference (ICI). To overcome these shortcomings as much as possible, in this paper, a novel symbol timing synchron...
