Mobile communication data has evolved voice and text to multimedia data as music, picture and video etc., which requires
high data rate and high quality of multimedia data. Multi-Carrier Code Division Multiple Access (MC-CDMA) has
focused on the next generation communication system that can realize high data rate and large capacity mobile communication
systems under multi-path fading environments. In conventional, it has considered about how to improve the performance of
BER with efficient data usage. However, it does not consider about transmitting the cross layer as Scalable Video Coding (SVC)
signal using MC-CDMA system. Scalable Video Coding (SVC) is composed one base layer and several enhance layers group.
Each video layer has differential priority (Base layer>1st Enhance layer >2nd Enhance layer). In addition, conventional research
has focused on the perfect CSI for video allocation. However, it is difficult to obtain perfect CSI in practical systems. Because
the wireless channel state has time-varying characteristics. Moreover, if it obtained a perfect CSI, the feedback delay time will
be increasing. As a result, the system is degraded the performance of BER by increased delay time. Therefore, we proposed the
SVC signal transmission scheme using Transmission Block Selection (TBS) with partial channel state information (PCSI) in
an MC-CDMA system. Proposed TBS scheme provides the base layer with the best protection by best performance sub-block
selection. Enhance layer selected next best performance sub-block. The proposed system can improve the Peak Signal to Noise
Ratio (PSNR) performance of the video communication compared to that of a conventional system.
