New Multiple Antenna Technique for Communication Systems

Abstract

The rapid and progressive development in the field of wireless communication has contributed to the advancement of the scientific research system in order to find solutions to many of the problems facing this field.One of the most important areas of scientific research is how to use multiple antennas to increase the capacity and efficiency of the spectrum. The emergence of the Multiple Input Multiple Output (MIMO) system has had a significant effect in reducing the problems of wireless communication such as interference and scattering which caused due to multipaths.However, MIMO systems are subject to several problems, including increased system complexity,excessive energy consumption and inter–channel interference. Spatial modulation (SM) is a transmission procedure proposed for MIMO frameworks, where just a single transmit antenna is dynamic at once, introducing an expansion in the spectral efficiency equivalent to the basetwo logarithms of the quantity of the number of transmit antennas. Recently, Quadrature Spatial Modulation (QSM) has been another MIMO scheme which depends on the extension of the spatial domain to another dimension by using both in-phase and quadrature segments from maybe a couple receiving antenna in the meantime.QSM gives the same error performance and spectral efficiency of SM with 3 dB less signal power while holding all its implicit in advantages. The aims of thesis are how to enhance the error performance of MIMO systems combines with Chip by Chip using interleaver detector. The thesis is concerned with the proposing new systems of MIMO scheme and comparing its performance with conventional frameworks. The performance of antenna array beamforming on Chip-Interleaved Co
