Abstract

This paper studies a Simultaneous Wireless Information and Power design based on two important concepts of energy harvesting and cognitive ratio two key aspects of transfer systems: simultaneous modulation of interference power and output power, and the asymmetric transmit-receive relationship that must exist in the primary user (PU). Building on previous findings about the effects of individual parameters on system behavior, exploring the impact of these combined alterations on interruption probability and system performance. First, the joint manipulation of interference power and output power is under investigation. Our analysis unveils nuanced shifts in interruption probability when both parameters are altered concurrently. By varying these factors within a range, Complex variations in outage probability are observed, underscoring the interplay between interference mitigation and energy availability. Secondly, the deviation of one-to-many communication between sender and receiver in PU integration is under study. This scenario mirrors a real-life situation where a single sender transmits information to multiple receivers. Through simulation and analysis, the effects of this asymmetric relationship on system reliability and interrupt probability are illustrated. This exploration pro-vides insights into the scalability and adaptability of secondary user systems to accommodate different modes of communication. By addressing these two dimensions, this study can contribute to a deeper understanding in real life of the complex interplay between related system parameters and communication dynamics in the secondary and primary users of this system. The findings provide valuable insights for designing and optimizing such systems in the real world, where adaptability and some resilience are critical.
