Orthogonal Space-Time Block Codes (OSTBC) and multiple-input-multiple-output (MIMO) communication system are new techniques with high performance that have many applications in wireless telecommunications. This chapter presents an image transfer technique for the unmanned aerial vehicle (UAV) in a UWB system using a hybrid structure of the MIMO-OSTBC wireless environment in multiple description coding (MDC) deals. MDC technique for image transmission is a new approach in which there is no record of it so far. This ensures that in the packet loss scenario due to channel errors, images with acceptable quality with no need for retransmission can be reconstructed. The proposed system is implemented using a different number of transmitter and receiver antennas UAV. Assuming a Rayleigh model for the communication channels, the MDC image transmission performance is compared with single description coding (SDC). Experimental results confirm that the proposed hybrid method has better performance than the SDC.
