Bifurcation analysis of ion-acoustic waves for Schrödinger equation in nonextensive Solar wind plasma

Bifurcation analysis of ion-acoustic wave (IAWs) solutions of the nonlinear Schrödinger equation (NLSE) is explored for the first time in an electron-ion (e-i) magnetized solar wind plasma. The existence of ion-acoustic (IA) periodic, superperiodic, kink, antikink, compressive and rarefactive solitary wave solutions are revealed. Special values of Solar wind plasma parameters at a normalized distance from the Sun are considered for numerical simulation. The IA wave solutions are derived analytically. These solutions are analyzed numerically considering the influence of parameters, namely, wave number (k), velocity (V) of traveling wave and nonextensive parameter (q). Computational simulation reveals that only IA periodic wave grows in amplitude as waves moves from the Sun.     

Interfering cell identification in satellite cellular system

Global satellite cellular system architecture utilizes a constellation of satellites, each with multiple spot beams/cells to provide coverage, and employs frequency reuse techniques to efficiently reuse the allocated spectrum. Identification of interfering cells of any satellite in the constellation is critical for cell management in order to provide interference-free communications services. The principles and techniques to identify the interfering cells are developed
