Pseudo-random sequences with good correlation properties and large linear span are widely used in code-division multiple-access (CDMA) communication systems and cryptology for reliable and secure information transmission. In this paper, sequences with long period, large complexity, balance statistics and low correlation properties are constructed from the addition of m-sequences with pairwise-p...

the kinetic of photo oxidative decolorization of c.i. acid yellow 23 (ay23) was investigated in uv/ process. the semi-logarithmic of the concentrations of ay23 versus irradiation time were linear, suggesting pseudo-first order reaction. a simple kinetic model is proposed which confirms pseudo- first order reaction. the results indicate that the apparent reaction rate constant is a function of l...

The pseudo-Wishart distribution arises when a Hermitian matrix generated from a complex Gaussian ensemble is not full-rank. It plays an important role in the analysis of communication systems using diversity in Rayleigh fading. However, it has not been extensively studied like the Wishart distribution. Here, we derive some key aspects of the complex pseudo-Wishart distribution. Pseudo-Wishart a...

In spread spectrum systems, pseudo-random (PN) sequences are used to spread the data bits. There are various type of PN sequences are available with good correlation properties, most of which are generated by Linear Feedback Shift Register (LFSR). In this paper we describe the generation pseudo chaotic sequences (PCS) and conventional PN sequences and its correlation properties. Here, pseudo-ch...

In this note we examine the solution and the impulsive behavior of autonomous linear multivariable systems whose pseudo-state β (t) obeys a linear matrix differential equation A (ρ)β (t) = 0 where A (ρ) is a polynomial matrix in the differential operator ρ := d dt . We thus generalize to the general polynomial matrix case some results obtained in [2][3] which regard the impulsive behavior of th...
