A telemetry system based on Haar functions

In this paper, a telemetry system based on Haar functions is described. According to the principles of orthogonal multiplexing, the key point is that non-interference between channels can be guaranteed if the subcarrier waveforms are chosen from an orthogonal set. The Haar functions form an orthogonal and orthonormal system of periodic square waves. The Haar functions can be used as subcarriers for a telemetry system. Finally, an experimental four-channel model has been constructed to demonstrate the principle.
