This paper investigates the optimal estimation problem in lossy networked control systems where the control packets are randomly dropped without acknowledgment. The system state follows a Gaussian mixture distribution with exponentially increasing terms. It is revealed that the stability is independent of the packet loss rate, and is not affected by the lack of acknowledgment. A suboptimal filter with improved computational efficiency is then developed.
