“…After we got the expression for the joint probability density, we can calculate channel capacity at the output of the macrodiversity system shown in Figure 1. The maximum data rate can be achieved after the channel has experienced all possible fading states during a sufficiently long transmitting time, which can be expressed as follows in the unit of bits per second, where B denotes channel bandwidth expressed in Hz [24], [25]:…”

In this paper macrodiversity system consisting of two microdiversity SC (Selection Combiner) receivers and one macrodiversity SC receiver are analyzed. Independent κ-μ fading and correlated slow Gamma fading are present at the inputs to the microdiversity SC receivers. For this system model, analytical expression for the probability density of the signal at the output of the macrodiversity receiver SC, and the output capacity of the macrodiversity SC receiver are calculated. The obtained results are graphically presented to show the impact of Rician κ factor, the shading severity of the channel c, the number of clusters µ and correlation coefficient ρ on the probability density of the signal at the output of the macrodiversity system and channel capacity at the output of the macrodiversity system. Based on the obtained results it is possible to analyze the real behavior of the macrodiversity system in the presence of κ-μ fading.

“…In the last twenty years, the TWDP model has been extensively studied theoretically [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Additionally, its existence is supported by practical evidence both in mmWave 5G communication networks equipped with directional antennas or arrays [21] and in wireless sensor networks deployed in cavity environments [22].…”

Two-wave with diffuse power (TWDP) is one of the most promising models for the description of small-scale fading effects in 5G networks, which employs mmWave band, and in wireless sensor networks deployed in different cavity environments. However, its current statistical characterization has several fundamental issues. Primarily, conventional TWDP parameterization is not in accordance with the model’s underlying physical mechanisms. In addition, available TWDP expressions for PDF, CDF, and MGF are given either in integral or approximate forms, or as mathematically untractable closed-form expressions. Consequently, the existing TWDP statistical characterization does not allow accurate evaluation of system performance in all fading conditions for most modulation and diversity techniques. In this regard, physically justified TWDP parameterization is proposed and used for further calculations. Additionally, exact infinite-series PDF and CDF are introduced. Based on these expressions, the exact MGF of the SNR is derived in a form suitable for mathematical manipulations. The applicability of the proposed MGF for derivation of the exact average symbol error probability (ASEP) is demonstrated with the example of M-ary PSK modulation. The derived M-ary PSK ASEP expression is further simplified for large SNR values in order to obtain a closed-form asymptotic ASEP, which is shown to be applicable for SNR > 20 dB. All proposed expressions are verified by Monte Carlo simulation in a variety of TWDP fading conditions.

“…The performance of transmissions over TWDP fading channels has been investigated in a number of publications: In [30], the authors investigated the biterror ratio performance of BPSK transmissions over TWDP fading channels, including maximum ratio combining (MRC) of multiple independent branches. In [31], the authors derived the outage probability of cooperative relay networks under TWDP fading, and, in [32], the author conducted a capacity analysis of TWDP fading channels. In [33], the authors derived analytic expressions for the average probability of successful energy detection based spectrum sensing over TWDP fading channels.…”

In this paper, we consider wireless transmissions over directional multiple-input single-output (MISO) two wave with diffuse power (TWDP) fading channels, subject to interference over the same type of channel. TWDP fading is known to exhibit an outage behavior that can be even worse than Rayleigh fading and has experimentally been observed in a number of vehicular channel measurement campaigns. To enhance the reliability of multi-point transmissions over MISO TWDP fading channels, we propose a zero-forcing based coordinated beamforming scheme, for which we can analytically characterize and optimize the outage probability of the multi-point transmissions. Based on the developed outage expressions, we furthermore propose a greedy coordinated scheduling approach that attempts to maximize the achievable rate of the system. Finally, we propose a transmission rate adaptation scheme for fixed size packet transmissions, which supports reliable and at the same time resource efficient multi-point transmissions.
