Energy efficiency of transmit diversity systems under a realistic power consumption model [PDF]

open access: yesIEEE Communications Letters, 2013
We compare the downlink energy efficiency of spatial diversity multiple transmit antenna schemes. We determine the minimum required transmit power for a given outage probability.

Circular shifted transmit diversity [PDF]

open access: yesWireless Communications and Mobile Computing, 2004
AbstractThree design requirements of space‐time block code, full diversity order, full data rate and orthogonality, cannot be achieved simultaneously when the number of transmit antenna is more than two. In this paper, we propose a transmit diversity scheme—circular shifted transmit diversity (CSTD).

New Statistical Results of Partial Sums of Ordered Gamma-Distributed RVs for Performance Evaluation of Wireless Communication Systems

open access: yesApplied Sciences, 2022
With the increase in the complexity of communication systems, order statistics have become increasingly significant in performance evaluation, especially for advanced diversity techniques over fading channels.

Wireless power transfer with transmit diversity [PDF]

open access: yesF1000Research, 2021
Background: Wireless power transfer is important for energizing and recharging the Internet-of-Things (IoT) cordlessly. Harnessing energy effectively from radio waves has become a crucial task. It is known that diversities at the transmitting antenna and waves (i.e.

Analysis of Distributed Transmit Diversity with Outdated Diversity Weights [PDF]

open access: yesMobile Information Systems, 2017
Distributed transmit diversity (DTD) technique that combines cooperative communications and diversity techniques is a suitable solution in 5th-generation (5G) systems. In this paper, we investigate the effect of receiver phase compensation (RPC) on the performance of DTD. We introduce new expressions for the average error rate of DTD in the presence of

Capacity Analysis of Channel Inversion Using Space-Time Block Coding with Transmit Power Control

open access: yesElektronika ir Elektrotechnika, 2022
In this paper, we analyze channel inversion with transmit diversity in terms of capacity and bit error rates in correlated fading. We obtain the Shannon capacity of Rayleigh fading channel under channel inversion using spatially correlated dual branch ...

A differential detection scheme for transmit diversity [PDF]

open access: yesIEEE Journal on Selected Areas in Communications, 2000
We present a transmission scheme for exploiting diversity given by two transmit antennas when neither the transmitter nor the receiver has access to channel state information. The new detection scheme can use PSK constellations and encoding is simple. At the receiver, decoding is achieved with low decoding complexity.
