Query: A nonlinear transform based analog video transmission framework   Soft-cast, a cross-layer design for wireless video transmission, is proposed
to solve the drawbacks of digital video transmission: threshold transmission
framework achieving the same effect. Specifically, in encoder, we carry out
power allocation on the transformed coefficients and encode the coefficients
based on the new formulation of power distortion. In decoder, the process of
LLSE estimator is also improved. Accompanied with the inverse nonlinear
transform, DCT coefficients can be recovered depending on the scaling factors ,
LLSE estimator coefficients and metadata. Experiment results show that our
proposed framework outperforms the Soft-cast in PSNR 1.08 dB and the MSSIM gain
reaches to 2.35% when transmitting under the same bandwidth and total power.
