ABSTRACT

Interference is considered as the major problem in the next-generation wireless systems to attain higher throughput. The conventional interference cancelation techniques attain a theoretical breach in endorsing the wireless systems. However, the interference in the signals causes an error or imprecise estimation of the channel for future fifth-generation (5 G) transmissions. Thus, this paper proposes a technique, named Fractional Sequential Likelihood Ascent Search (Fractional-SLAS) for mitigating the interference in massive Multiple Input Multiple Output (MIMO) systems in 5 G technology. The proposed Fractional-SLAS is the integration of Fractional calculus (FC) and Sequential Likelihood Ascent Search Detector (SLAS). Initially, the signals are transmitted through the transmitter and undergo the encoding and modulation process. Then, the obtained modulated signals are fetched using the transmitting antenna that transmits the signals to the receiver. At the receiver side, interference is generated due to the number of cross antennas. Thus, the interference in the signals is eradicated by applying the proposed Fractional-SLAS at the receiver end. Hence, the proposed interference mitigation method is completely eradicated from the signals without any delay or loss in the quality of the transmitted signal. The proposed Fractional-SLAS provides superior performance with minimal Bit Error Rate (BER), Symbol Error Rate (SER), and throughput with values 0.00006 dB, 0.00006 dB, and 0.96 bps.

5G 技术中大规模 MIMO 系统干扰消除的分数序列似然上升搜索检测器

摘要

干扰被认为是下一代无线系统中获得更高吞吐量的主要问题。传统的干扰消除技术在支持无线系统方面达到了理论上的突破。然而,信号中的干扰会导致错误或对未来第五代 (5G) 传输的信道估计不精确。因此,本文提出了一种名为分数顺序似然上升搜索 (Fractional-SLAS) 的技术,用于减轻 5G 技术中大规模多输入多输出 (MIMO) 系统中的干扰。所提出的分数 SLAS 是分数微积分 (FC) 和顺序似然上升搜索检测器 (SLAS) 的集成。最初,信号通过发射机传输并经过编码和调制过程。然后,使用将信号发送到接收器的发送天线获取获得的调制信号。在接收端,由于交叉天线的数量,会产生干扰。因此,通过在接收端应用所提出的分数 SLAS 来消除信号中的干扰。因此,所提出的干扰减轻方法从信号中完全消除,而传输信号的质量没有任何延迟或损失。建议的分数 SLAS 提供卓越的性能,具有最小的误码率 (BER)、符号错误率 (SER) 和值为 0.00006 dB、0.00006 dB 和 0.96 bps 的吞吐量。通过在接收端应用建议的分数 SLAS,消除信号中的干扰。因此,所提出的干扰减轻方法从信号中完全消除,而传输信号的质量没有任何延迟或损失。建议的分数 SLAS 提供卓越的性能,具有最小的误码率 (BER)、符号错误率 (SER) 和值为 0.00006 dB、0.00006 dB 和 0.96 bps 的吞吐量。通过在接收端应用建议的分数 SLAS,消除信号中的干扰。因此,所提出的干扰减轻方法从信号中完全消除,而传输信号的质量没有任何延迟或损失。建议的分数 SLAS 提供卓越的性能,具有最小的误码率 (BER)、符号错误率 (SER) 和值为 0.00006 dB、0.00006 dB 和 0.96 bps 的吞吐量。
