  1. Kalman Filter Homework 2 • Generate a Kalman Filter for simulated data • The equations are: • Note that the measurement has signal-dependent noise • Assume that the system can fall under different “states”. These states will be defined through different A and noises. You will be given these values • The system transitions between different states. The transition times are specified. • You are given:, and y(k)

  2. States

  3. State 1 State 2 State 3 State 4

  4. Task: • For each state, defined on the next slide, calculate the steady state that the Kalman Gain will converge to. • Write and implement a Kalman Filter. Note that the measurement noise is signal-dependent. • At each state transition, change your A matrix and noises appropriately • Your estimates of x and P at the end of each state will carry over into the next state. • Compare your final Kalman Gain at the end of each state with your analytically calculated value • Also compare the Kalman Gain at each iteration to the “gain” of an LMS algorithm (plot and compare these two gains)
