چکیده

Adaptive modulation (AM) technique may make more promote in the execution of wireless communication systems through adaptively conformity transmitter parameters to fading channels; therefore, it has been taken as one of the key physical techniques. Error performance and throughput in MIMO wireless systems can be improved through the use of Adaptive Modulation. Adaptive modulation selection plays an important role in wireless communication since the wireless channel conditions vary progressively. This paper offers a general overview of the adaptive modulation scheme in wireless multiple-input multiple-output (MIMO) systems.

Frequency-Domain Eigenbeam-SDM and Equalization for Single-Carrier Transmissions

In mobile communications, the channel consists of many resolvable paths with different time delays, resulting in a severely frequency-selective fading channel. The frequency-domain equalization (FDE) can take advantage of the channel selectivity and improve the bit error rate (BER) performance of the single-carrier (SC) transmission. Recently, multi-input multi-output (MIMO) multiplexing is gai...

Modeling and Performances Evaluation of HARQ Technique for MIMO Transmission in Downlink LTE Cellular Networks

Long Term Evolution (LTE) is designed for deployment in a variety of spectrum allocation ranging from 1.4 MHz to 20 MHz. The peak data rate envisaged for LTE is 100 Mbps in downlink and 50 Mbps in the uplink. Unfortunately, different constraints have a strong influence on system performance such as the velocity of user equipment and effect of multipath channel. To achieve data rate compliance w...
