In the recent days, the multiple input multiple output (MIMO) is considered as the important technology of wireless due to its characteristics. The channel selection and scheduling plays an important roles in MIMO communication systems. For this purpose, various techniques are proposed in the traditional works, but it has some major drawbacks such as increased bit error rate, inefficient channel selection, and reduced spectral efficiency. In order to overcome these issues, this paper aims to develop a new optimization based scheduling technique for a successful MIMO communication. At first, the Rayleigh fading channel is initialized and its parameters are extracted, then the beamforming technique is used to extract the features. After that, the optimal channel is selected from the available number of channels by implementing a joint optimization (JO) technique. Consequently, the power spectral density is estimated before scheduling the channel for communication. Finally, the sub-band expediency based scheduling (SES) technique is implemented for scheduling the channel based on the priority. The novel concept of this paper are, an optimal channel is selected based on the correlation coefficient value, and the priority based channel scheduling is performed for communication. The experimental results evaluate the performance of the proposed JO-SES technique based on the measures of BET, SNR, and average sum rate. Also, some of the existing techniques are considered in this work for proving the betterment of the proposed technique.

基于联合优化的MIMO通信系统子带权宜调度技术

近年来,由于其特性,多输入多输出(MIMO)被认为是无线的重要技术。信道选择和调度在MIMO通信系统中起重要作用。为此,在传统作品中提出了各种技术,但是它具有一些主要缺点,例如误码率增加,信道选择效率低和频谱效率降低。为了克服这些问题,本文旨在为成功的MIMO通信开发一种基于优化的新调度技术。首先,初始化瑞利衰落信道并提取其参数,然后使用波束成形技术提取特征。之后,通过实施联合优化(JO)技术,从可用的通道数中选择最佳通道。因此,在调度用于通信的信道之前,估计功率谱密度。最后,实现了基于子带便捷性的调度(SES)技术,用于基于优先级调度信道。本文的新颖概念是,基于相关系数值选择最佳信道,并执行基于优先级的信道调度以进行通信。实验结果基于BET,SNR和平均求和率的度量来评估所提出的JO-SES技术的性能。另外,在这项工作中考虑了一些现有技术,以证明所提出技术的改进。在调度用于通信的信道之前,估计功率谱密度。最后,实现了基于子带便捷性的调度(SES)技术,用于基于优先级调度信道。本文的新颖概念是,基于相关系数值选择最佳信道,并执行基于优先级的信道调度以进行通信。实验结果基于BET,SNR和平均求和率的度量来评估所提出的JO-SES技术的性能。另外,在这项工作中考虑了一些现有技术,以证明所提出技术的改进。在调度用于通信的信道之前,估计功率谱密度。最后,实现了基于子带便捷性的调度(SES)技术,用于基于优先级调度信道。本文的新颖概念是,基于相关系数值选择最佳信道,并执行基于优先级的信道调度以进行通信。实验结果基于BET,SNR和平均求和率的度量来评估所提出的JO-SES技术的性能。另外,在这项工作中考虑了一些现有技术,以证明所提出技术的改进。本文的新颖概念是,基于相关系数值选择最佳信道,并执行基于优先级的信道调度以进行通信。实验结果基于BET,SNR和平均求和率的度量来评估所提出的JO-SES技术的性能。另外,在这项工作中考虑了一些现有技术,以证明所提出技术的改进。本文的新颖概念是,基于相关系数值选择最佳信道,并执行基于优先级的信道调度以进行通信。实验结果基于BET,SNR和平均求和率的度量来评估所提出的JO-SES技术的性能。另外,在这项工作中考虑了一些现有技术,以证明所提出技术的改进。
