This paper extends some approximation methods that are used to identify closed form Bit Error Rate (BER) expressions which are frequently utilized in investigation and comparison of performance for wireless communication systems in the literature. By using this group of approximation methods, some expectation integrals, whose exact analyses are intractable and whose Monte Carlo simulation computations have high complexity, can be computed. For these integrals, by using the sampling property of the integrand functions of one or more arguments, reliable BER expressions revealing the diversity and coding gains are derived. Although the methods we present are valid for a larger class of integration problems, in this work we illustrate the method by showing the step by step derivation of the BER expressions for a canonical cooperative communication scenario as well as a network coded system scenario. The derived expressions agree with the simulation results for a very wide range of signal-to-noise ratio (SNR) values.

This work presents approximation methods that are used to identify Bit Error Rate (BER) expressions which are frequently utilized in investigation and comparison of performance for wireless communication systems in the literature. In this group of approximation methods, some expectation integrals, which are complicated to analyze and time-consuming to evaluate through Monte Carlo simulations, are handled. For this group of integrals, by using the sampling property of the Q-function under mid- and high- Sign...
Decomposition of the mean squared error and NSE performance criteria: Implications for improving hydrological modelling
Gupta, Hoshin V.; Kling, Harald; Yılmaz, Koray Kamil; Martinez, Guillermo F. (2009-10-20)
The mean squared error (MSE) and the related normalization, the Nash-Sutcliffe efficiency (NSE), are the two criteria most widely used for calibration and evaluation of hydrological models with observed data. Here, we present a diagnostically interesting decomposition of NSE (and hence MSE), which facilitates analysis of the relative importance of its different components in the context of hydrological modelling, and show how model calibration problems can arise due to interactions among these components. T...
Investigation of a method to identify energy efficient organization of compression unit in parallel tree multipliers
Rashid, Muhammad Saleh; Muhtaroğlu, Ali; Sustainable Environment and Energy Systems (2018-1)
In this study, high-performance integer multipliers extensively used in digital signal processing are investigated in the context of energy-aware system organization. Among different functional blocks in an integer multiplier, the compression unit is primarily targeted for optimization as the largest section of the multiplier with significant energy consumption. Five different realizations of the most popular Wallace tree are investigated in this work, which consists of Dual Pass Logic (DPL) circuit impleme...
A Novel Software for Automatic Calibration Factor Measurement of RF Power Sensors
Kizilbey, Oguzhan; Arslan, Murat; Bayrak, Yusuf; Çetinkaya, Anıl; Yugruk, Aydin; Danaci, Erkan (2022-01-01)
In this letter, a software for calibration factor (CF) measurement of radio frequency (RF) power sensors (PS) by using VNA-based direct comparison transfer method (VBDCTM) was developed on C# platform. Measurements were performed between 10 MHz and 18 GHz frequency range. When the calibration factors calculated with conventional CF measurement method and novel software were compared, a maximum difference of 4.56% was found in the 10 MHz - 18 GHz frequency band. Therefore, the automatic CF measurement softwa...
Analysis of the performance of network coding using the sampling property of Q-function Ǎg Kodlama için q-fonksiyonun örnek alma özellǐginden yararlanarak başarim analizi
Aktaş, Tǔgcan; Yılmaz, Ali Özgür; Aktaş, Emre (2013-08-05)
In the area of cooperative and network coded communication that naturally arises from cooperation, which become increasingly important in wireless communications, the expected end-to-end bit error rate (BER) values are frequently required to compare the proposed coding, relaying, and decoding techniques. Instead of obtaining these values through time consuming Monte Carlo simulations, deriving the closed form expressions via approximations is also crucial. In this work, we make use of the sampling property ...
