About this book
Adaptive Video Transmission over Wireless MIMO System by Floriano De Rango; Institute for New Technologies (Maastricht, Netherlands) is a book available to read on EtoBox.
Video transmission over MIMO systems offers numerous new research opportunities. Lots of new researches are originated from the fundamental change in data transmission from single link to multiple simultaneous links in the MIMO systems. In this study, we applied joint source-channel coding with modulation scheme to design an adaptive video transmission over wireless MIMO system. The bit rates of MPEG2 video can be adaptive to associate with the convolutional channel codes and space-time block code (STBC) under the channel capacity constraint consideration. In order to be consistent with the channel capacity constraint (which is set to be 1 bit/transmission), there are three rate combination types of the joint source-channel coding algorithm as shown in Table 1. From the simulation results, we found that the space diversity and the channel code rate both are important factors influenced reconstructed video quality. The simulation results shows that two transmitter antennas and two receiver antennas (2×2) STBC coded system demonstrates the best BER performance, while the worst performance goes to the 2×1 STBC coded system. The system performance is also improved with lower channel co
