Diversity Order and Coding Gain of General-Order Rectangular QAM in MIMO Relay With TAS/MRC in Nakagami- $m$ Fading

Recently, multiple-input–multiple-output (MIMO) relay networks have been an active area of research, particularly with combining single transmit antenna selection (TAS) and receiver maximal ratio combining (MRC). Moreover, generalorder rectangular quadrature amplitude modulation (QAM) has received much attention for its high spectral efficiency and flexible modulation scheme. However, the analy...

Systolic like soft-detection architecture for 4×4 64-QAM MIMO system

MIMO systems (with multiple transmit and receive antennas) are becoming increasingly popular, and many next-generation systems such as WiMAX, 3-GPP LTE and IEEE802.11n wireless LANs rely on the increased throughput of MIMO systems with up to four antennas at receiver and transmitter. High throughput implementation of the detection unit for MIMO systems is a significant challenge especially for ...

Capacity Analysis of the VBLAST MIMO System in Fading Condition with M-QAM Modulation

Multiple input multiple output (MIMO) system using multiple transmit and receive antennas are widely recognized as the vital breakthrough that will allow future wireless systems to achieve higher data rates and also to increase diversity to combat channel fading. Therefore, a MIMO system can provide capacity gain and diversity gain. In this paper, we investigate the channel capacity issue of th...

Energy-Efficient M-QAM Precoder Design with Spatial Peak Power Minimization for MIMO Directional Modulation Transceivers

Spectrally efficient multi-antenna wireless communications is a key challenge as service demands continue to increase. At the same time, powering up radio access networks increases CO2 footprint. Hence, for an efficient radio access design, we design a directional modulation precoder for M QAM modulation with M = 4, 8, 16, 32. First, extended detection regions are defined in these constellation...
