Quadrature amplitude modulation is a method of combining two amplitude-modulated signals into a single channel, thereby doubling the effective bandwidth. QAM is used with pulse amplitude modulation in digital systems, especially in wireless applications

When I first studied Kalman filtering, I saw many advanced signal processing submissions here at the MATLAB Central File exchange, but I didn t see a heavily commented, basic Kalman filter present to allow someone new to Kalman filters to learn about creating them. So, a year later, I ve written a very simple, heavily commented discrete filter.
