With the introduction of multiple transmit and receive antennas in the next generation wireless standards, real-time image and video communication is expected to become more common. New joint transmission and coding schemes are expected to be developed combining advantages of multiple antenna systems with source statistics. Based on this idea, we present an unequal power allocation scheme for transmission of JPEG compressed images over multiple-input multiple-output systems employing spatial multiplexing. Results show that our unequal power allocation scheme provides significant image quality improvement as compared to different equal power allocations schemes.
