Multiple transmit and receive antenna systems have improved the reliability as well as data rate in a wireless communication system. Such advanced wireless architectures have empowered smart devices to fulfill the demand of multimedia content. Image is a major user generated content in wide range of applications, hence reliable transmission of image is an important research problem. New transmission and coding schemes that explore advantages of multiple antenna systems matched with source statistics have been developed. Based on a similar idea, an equal power allocation scheme for transmission of compressed images over multiple-input multiple-output (MIMO) systems employing partial repetition coding is proposed. The JPEG compression algorithm divides image into different quality layers. The proposed system repeats transmission of high quality data from more than one antenna as compared to the lower quality data which is transmitted using one antenna at most, in a particular time slot. A heuristic spatial multiplexing scheme is also proposed to optimally divide the bit stream chunks for transmission. Extensive simulations have shown that equal power allocation and repetition coding scheme is better as compared to reference schemes.
