Spectral Efficient Spatial ModulationTechniques
Space modulation techniques (SMTs) have emerged as promising candidates for spectral- and energy-efficient wireless communication systems since they strike a good balance among error performance, power efficiency, spectrum efficiency, and receiver complexity. In SMTs, the information is not only conveyed by the habitual M-ary signal constellations; rather, it is also conveyed by the indices of the transmit antennas. As such, ... إقراء المزيد

Low Density Parity Check (LDPC) Coded MIMO-Constant Envelop Modulation System with IF sampled 1-bit ADC

Low Density Parity Check (LDPC) Coded MIMO-Constant Envelop Modulation System with IF sampled 1-bit ADC
MIMO-Constant Envelop Modulation (CEM) is a very power and complexity efficient system, which is introduced as alternative candidate to the currently used MIMO-Orthogonal Frequency Division Multiplexing (OFDM). CEM system enables to use high efficient nonlinear power amplifier on the transmitter side and 1 bit (low resolution) analog to digital converter (ADC) on the receiver side. Due to adopting the low ... إقراء المزيد

Higher Order Modulation Scheme for the 1-bit ADC MIMO-Constant Envelope Modulation

Higher Order Modulation Scheme for the 1-bit ADC MIMO-Constant Envelope Modulation
The low power consumption merit of the multi-input multi-output constant envelope modulation (MIMO-CEM) system nominated it to be a favorable candidate to design the PHY layer of the low power smart devices that support the internet of things (IoT) technology. Thanks to the CEM, the MIMO-CEM system efficiently overcomes the high peak-to-average power ratio (PAPR) in the transmitter side (TX). ... إقراء المزيد

Fully Generalised Spatial Modulation

Fully Generalised Spatial Modulation
This paper introduces a novel multiple-input–multiple-output (MIMO) modulation technique named fully-generalised spatial modulation (F-GSM). The proposed F-GSM vanquishes the pivotal criticism of the conventional spatial modulation (SM) and generalised spatial modulation (GSM) techniques which constraints the data rate increment to be proportionated with the base-two logarithm of the number of the transmit antennas ( ). This logarithmical proportion regrettably, makes ... إقراء المزيد

Fully-Quadrature Spatial Modulation

Fully-Quadrature Spatial Modulation
In this paper, a new multiple-input multiple-output (MIMO) modulation scheme termed as fully-quadrature spatial modulation (F-QSM) is proposed. The F-QSM is a class of space modulation techniques (SMTs) that harness the spatial positions of the transmit antennas in the transmit antenna array to fulfill high data rates. However, the data rates of most of SMTs are restricted to be logarithmically ... إقراء المزيد
