To improve performance in the 64-QAM multicarrier communication system, we propose a
new method, closed-loop rotate modulation. The closed-loop process requires feedback …

The emerging Internet of Things will make the next generation 5G systems to support a
broad range of diverse needs with greater efficiency requirements. The new class of …

Bandwidth is very important in communication system, and it is a limited resource. In order to
save the limited bandwidth resource, high order M-ary modulation is widely employed in …

A lot of attention has been given recently to future multicarrier (MC) modulation techniques,
for high speed robust wireless systems, in order to serve upcoming envisioned needs …

In this paper we describe the overall idea and results of a recently proposed radio access
technique based on filter bank multicarrier (FBMC) communication system using two …

Multi-level Quadrature Amplitude Modulation is one of the most popular modulation
technique in the satellite channel for its spectral efficiency in limited bandwidth …

The performance of multiple-input multiple-output (MIMO) systems can be enhanced with the
availability of channel direction information at the transmitter. One of the known techniques …

More and more attention has been paid on the issue of bandwidth utilization. Nowadays,
with limited frequency spectrum resources, the capacity of traditional communication system …

We present the first real-time transmitter generating a multicarrier offset-QAM signal at 224
Gb/s after polarization multiplexing. Low penalties are achieved in a back-to-back …

Because of the complex electromagnetic propagation phenomena and the requirement of
more and more bandwidth, the importance of studying the wireless channel becomes more …
