PAC coding for real-time video transmission over mobile radio environment

To overcome the bandwidth limitation and to strengthen the channel effect immunity, a cube-based polynomial video coding scheme for mobile radio transmission is derived, named three-dimensional polynomial approximation coding (3D PAC). It also possesses the features of low bit rate of transmission data, robustness for channel fading and simple computation scheme for real-time processing. Compared with the videophone standard H.261, it gains advantage on resisting channel noise to 2 dB with same bit rate, and the superior subjective performance may be obtained.
