A Novel Unequal Error Protection Scheme for 3-D Video Transmission Over Cooperative MIMO-OFDM Systems
Currently, there has been intensive research to drive Three-Dimensional (3-D) video technology over mobile devices. Most recently, Multiple Input Multiple Output (MIMO) with Orthogonal Frequency Division Multiplexing (OFDM) and cooperative diversity have been major candidates for the fourth-generation mobile TV systems. This paper presents a novel Unequal Error Protection (UEP) scheme for 3-D video transmission over cooperative MIMO-OFDM systems. Several 3-D video coding techniques are investigated to find the best method for 3-D video transmission over the error-prone wireless channels. View plus Depth (VpD) has been found the best technique over other techniques such as Simulcast Coding (SC) and Mixed-Resolution Stereo Coding (MRSC) in terms of the performance. Various UEP schemes are proposed to protect the VpD signals with different importance levels.
