This paper proposes resource allocation method for transmitting video streams intended to multiple users over time-varying wireless channel. Medium grain scalable video coding is employed to compress the video streams. The video coding method provides packets which can be dropped for bit rate adaptation at the cost of decoded video quality. This paper also employs adaptive modulation. It can provide...
Orthogonal frequency division multiplexing provides frequency diversity gain when assuming frequency selective channel which happens in most cases of wireless mobile communications. The frequency diversity can be utilized by considering data which requires unequal protection. Video data coded by scalable video coding method is an example. The video coding method encodes a certain picture period termed...
