Abstract	A scalable video delivery transmission framework over MIMO OFDM wireless channels by combining power allocation and antenna selection scheme has been proposed. The framework consisting of independently decodable layers (3D ESCOT), UEP channel coding structure, and antenna selection scheme provide more system error resilience even during deep fading period in wireless channels. A new algorithm is proposed to obtain the optimal power allocation and optimal transmission rate allocation among multiple layers, subject to constraints on the total transmission rate and the total power level. This proposed joint power allocation and antenna selection algorithm in MIMO OFDM system enables us to both overcome the challenge of the full CSI that was assumed in the existing approaches and utilize the estimated CSI from the receiver so as to achieve the optimal solution for a video bitstream in terms of its total expected distortion. Generally, as the wireless channel conditions change, the framework we proposed can scale the video streams and transport the scaled video streams to receivers with a smooth change of perceptual quality.
