In first seminar, we had analyzed cellular networks in generalized κ-μ shadowed fading using metrics such as coverage probability and error vector magnitude (EVM). We had derived these metrics assuming the interferers are independent. But in reality, interferers could be correlated. In this seminar, we will analyze the impact of correlated interferers on error vector magnitude. We will analytically show that correlation among interferers reduces the error vector magnitude. Also, we show the impact of fading parameters on EVM depends on correlation too.
Most of the work in literature has focused on EVM in single-input-single-output case. In the second part of the talk, we will analyze error vector magnitude in multiple-antenna scenarios i.e. i) single-input-multiple-output selection combining system and ii) multiple-input-single-output Alamouti coding system. We observe that the effect of shadowing is negligible in multi-antenna scenarios.
In device-to-device (D2D) communication, D2D links experience shadowing due to human body and hence has been experimentally observed to experience κ-μ shadowed fading. So, using these metrics derived for generalized κ-μ shadowed fading, we will finally analyze the impact of human body shadowing on D2D communication.
