Description: This thesis presents simulation data on array operation in wideband communication systems.
It is shown that array structures with closer inter-element spacing outperform structures with
much larger inter-element spacing. It is also shown that circular structures outperform linear
structures. This performance di erence between the classi cations of arrays is due largely
to the circular array s ability to handle high levels of interference. Even though a diversity
combining scheme (MRC) was used in the simulator, the arrays provided interference rejection
capabilities due to the closely spaced antenna elements. Platform: |

Description: 一篇非常实用的无线通信方向的文献，是关于cdma系统中doa估计的经典-The use of antenna arrays in wireless communications
makes it possible to estimate the directions of arrival (DOAs)
of impinging waveforms. The latter can be exploited to enhance
channel estimation accuracy or as an input for advanced mobile
positioning systems. In this paper, we consider the uplink of a
multicarrier code-division multiple-access (MC-CDMA) network
in which the base station is endowed with multiple receiving antennas
arranged in a uniform linear array. Transmission takes place
over a multipath channel, and the goal is the joint estimation of
the channel responses and DOAs of the uplink signals. In doing so,
we follow a maximum-likelihood (ML) approach and assume that
users transmit orthogonal training sequences to facilitate the task
of separating the signals. This way, all unknown parameters are
estimated independently of each other with affordable complexity.
Theoretical analysis and computer simulations are used to assess
the performance of the propose Platform: |

Description: Linear Antenna arrays provide alternative solution
to dimensional structure of Antennas such as paraboloidal
cylinders, paraboloids, offset focus paraboloids etc. This paper
presents the survey of various evolutionary approaches for linear
array optimization like genetic algorithm, Particle swarm
optimization, Simulated Annealing, Bacteria Foraging and
Biogeography Based Optimization. From the survey It was
observed that biogeography based optimization is better for
antenna geometries. Platform: |
