Backscatter communications have two major antenna configurations: the bistatic
configuration, in which the reader employs two different sets of antennas to transmit and …

Backscatter communications have received increasingly attention in Internet of Things (IoT)
due to its advantages of requiring no internal battery and almost zero maintenance …

Future backscatter RFID systems are required to be more reliable and data intensive for
emerging fields such as Internet of Things (IoT). Motivated by this, orthogonal space-time …

Recently unitary query (UTQ) was introduced to exploit the query diversity for the multiple-
input multiple output backscatter radio-frequency identification communications. Compared …

针对全硬件的传统相位测量方法中电路本身的温度漂移, 干扰信号及噪声等使测量结果产生误差
的问题, 结合LabVIEW 功能强大, 程序开发周期短, 图形化编程简单直观以及相关法抗干扰能力 …

In this work, we have demonstrated transmit diversity using phase conjugating scheme. A six
bit digital phase shifter and three voltage controlled phase shifters were developed to …

A new antenna diversity circuit is presented for maximum ratio combining of C2X antennas
at 5.9 GHz. The circuit allows phase alignment in a range between 0° and 360° as well as …

This paper introduces a special method to construct channel coefficient for describing the
general channel correlation scenario in the multiple-input multiple-output (MIMO) radio …

Because of the emerging field of Internet of Things (IoT), future backscatter RFID is required
to be more reliable and data intensive. Motivated by this, orthogonal space-time block code …

Backscatter modulation is the keystone behind the technical and commercial success of
Radio Frequency IDentification (RFID) in applications that require fast, efficient, and …
