This article presents multiple channel estimation (MCE) that is a multi-sensor access wireless system model. An avionics wireless system needs a power control device to match the power received from the multiple sensors. Without a power control device, the aircraft control unit is unable to receive the signals from sensors due to signal reflections, refraction and transmission loss. The MCE system is designed to suppress multi-sensor signal noise and interference while a sensor, with lower power than the other sensors, is received. This article investigates overcome the power difference based on the MCE system. The performance of proposed MCE model is investigated and validated for a safe indoor avionics wireless system and it improves the overall performance of the wireless system to perfect power stability.
