Effective unequal protection for a WiMAX video service

In a compact urban region, fixed WiMAX (IEEE 802.16d) burst profiles can be adaptively selected according to the picture type of packets from an arriving encoded video stream. Because additional protection of anchor picture packets reduces the data rate, an algorithm dynamically selects less favourable burst profiles for less important packets. Under the stringent Stanford University Interim channel model, this simple scheme achieves as much as ten dB gain in video quality at the receiver, along with reduced delay, compared to non-adaptation.
