“…This model has been investigated in numerous studies, [10][11][12][13] but in recent years it has attracted a great deal of interest and has been proposed in modeling millimeter-wave communication channels. [14][15][16][17][18][19] The primary disadvantage of this distribution is that its probability density and cumulative distribution function (CDF) are approximate. Recently, exact PDF and CDF of TWDP fading channel were introduced in Reference 20, but their suggested expressions are also in the form of infinite series.…”

SummaryThere are many aspects concerning a new generation of communication systems that most existing channel models cannot address. For instance, the positioning of the transmitter and receiver is such that a large number of specular components are observed in the receiver due to the use of small cells. The two‐wave with diffuse power (TWDP) distribution is a model for the fading channel when two specular waves with many scattering components are present. The primary issue with this distribution is that its principal statistics are approximated. In this paper, precise analytical expressions for the statistics of this distribution are proposed. The proposed expressions only contain one multivariate Fox's ‐function term instead of the earlier approximations that included several complex mathematical functions like Legendre and Laguerre. The second issue with TWDP is that this model includes no more than two specular components, which in many environments is insufficient. Therefore, its generalization, that is, N‐wave with diffuse power (NWDP), is required. This channel‐fading model contains N specular components and multiple scattering components. This paper also calculates exact expressions for this distribution's statistics. In addition, the bit error rate (BER) for coherent and noncoherent modulations is calculated with the NWDP distribution for fading channel.

A Nonlinear MIMO-OFDM Based Full-Duplex Cooperative D2D Communications System

et al. 2021

View full text Add to dashboard Cite

Multiple input multiple output (MIMO) based orthogonal frequency division multiplexing (OFDM) has widely been used in a wireless communications system for its robustness to frequency-selective channels and better spectral efficiency. The introduction of full-duplex (FD) and device-to-device (D2D) communications, which are potential candidates of fifth-generation (5G) and beyond, further improve the spectral efficiency of MIMO-OFDM based systems. This paper proposes a novel MIMO-OFDM based FD Cooperative-D2D (C-D2D) communications system wherein a cellular user (CU) acts as an FD relay to facilitate seamless communications between D2D transmitter and receiver. The complete analytical framework is presented to analyze the end-to-end performance of the proposed system. Specifically, the closed-form expression for symbol error rate (SER) of the proposed system is derived in the presence of multipath Rayleigh fading channel and residual self-interference (RSI) due to the FD mode. Further, the performance of the system is analyzed in the presence of a nonlinear high power amplifier (HPA) which introduces the nonlinear distortion. Finally, simulation results are presented to verify the derived expressions. The results show that there is higher SER in the presence of nonlinear HPA due to nonlinear distortion, which can be reduced by increasing input back off (IBO). The presence of RSI also increases the SER at CU, which is further reduced by employing self-interference cancellation (SIC) techniques. A complete end-to-end analytical framework is designed to compare the performance of the proposed system with the conventional system with linear HPA and no RSI.
