Detection of Load-Modulated Multiuser MIMO Signals
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A load modulated MIMO transmitter uses a single central power amplifier and tunes the antenna loads according to the information signal, eliminating the need for traditional RF chains (consisting of DACs, mixers, filters) at the transmitter. In this letter,...

2018 Edition, Volume 7, April 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A load modulated multiple-input multiple-output (MIMO) transmitter uses a single central power amplifier and tunes the antenna loads according to the information signal, eliminating the need for traditional radio frequency (RF) chains (consisting of DACs,...

Achieving MIMO performance with single-antenna radios
2010 Edition, October 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Multiple-antenna systems have been shown to provide significant performance improvements over single-antenna systems. Theoretical analysis, simulation and experimental testing corroborate improvements in capacity and transmit power/energy savings. Unfortunately, co-located MIMO radios...

On the design of a broadband wireless MIMO-OFDM demonstrator
2006 Edition, November 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We present an experimental broadband wireless 4+ù4 multiple-input multiple-output (MIMO) space-timeblock-coded (STBC) OFDM system based on an extension of the IEEE 802.11a/g physical layer (PHY) to multiple-antenna scenarios. In the RF section, a new custom,...

MIMO receiver system using single RF front-end
2014 Edition, February 1, 2014 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Conventional MIMO (multiple input multiple output) system is required to a number of RF chains as much as a number of antennas. If a number of antennas increased then a number of RF chains increased. Therefore, it is difficult to apply conventional...

Simple 2 × 2 MIMO 60-GHz Optical/Wireless System With Extending Fiber Transmission Distance
2014 Edition, Volume 32, October 15, 2014 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a simple 2 × 2 multiple-input multiple-output (MIMO) 60-GHz radio-over-fiber system. Due to the proposed specific frequency arrangement of driving signals, each optical transmitter requires only a single-drive Mach-Zehnder modulator with 3-dB...

Radio Frequency Based Direction Sensing Using Massive MIMO
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Navigation systems have been widely used in modern applications in which the moving speed and direction estimations are two key steps. Instead of using traditional device-based orientation sensor such as accelerometer and magnetometer to estimate the moving direction, this...
