Upper union bound for the decoding error probability of polar codes with arbitrary binary kernels under the successive cancelation decoding is derived. The proposed approach is based on the representation of polar codes as multilevel ones.

The recent sovereign debt crisis raises a debate on whether the cancelation of sovereign debt is compatible with democracy. Scholars opposed to the cancelation of sovereign debt refer to the Glorious Revolution of 1688, in which the British government began to make the people as a whole liable for the obligations incurred by their government. These scholars argue that this commitment formed the...

Generation of the auditory steady state responses (ASSR) is commonly explained by the linear combination of random background noise activity and the stationary response. Based on this model, the decrease of amplitude that occurs over the sequential averaging of epochs of the raw data has been exclusively linked to the cancelation of noise. Nevertheless, this behavior might also reflect the non-...

In this paper we consider physical-layer network coding (PLNC) in OFDM-based two-way relaying systems. Practically, a key impairment for the application of PLNC is the carrier frequency offset (CFO) mismatch between the sources and the relay, which can not be compensated completely in the multiple-access (MA) phase. As this CFO mismatch results in inter-carrier interference (ICI) for OFDM trans...

We investigate the Hawking radiation of black p-branes of superstring theories using the method of anomaly cancelation, specially, we use the method of [S. Iso, H. Umetsu and F. Wilczek, Phys. Rev. Lett. 96, 151302 (2006); Phys. Rev. D 74, 044017 (2006)]. The metrics of black p-branes are spherically symmetric, but not the Schwarzschild type. In order to simplify the calculation, we first make ...

Orthogonal frequency division multiplexing (OFDM) now a day is becoming a popular modulation technique for cognitive radio networks (CRN). It is only because it can provide large data rates and is sufficiently robust in the face of radio channel impairments. Digital modulation techniques provide efficient evolution for our wireless mobile communications by increasing the capacity, speed and qua...

Let h(y) be a bounded radial function and Ω (y) an H function on the unit sphere satisfying the cancelation condition. Then the Marcinkiewicz integral operator μΩ related to the Littlewood-Paley g−function is defined by

Adaptive systems are employed in the cancelation of noises and estimation of periodic and quasi periodic signals. Amongst these signals are the electrocardiogram (ECG),impedance cardiography, brain evoked potentials and modulated signals in telecommunication applications. In this paper we study the behaviour of the weights of the LMS algorithm when used to estimate the coefficients of the discr...

New estimates of the potentials solutions to compressible Navier-Stokes equations are derived. The result obtained applied boundary value problems for with critical adiabatic exponents. cancelation concentrations kinetic energy density is proved
