The wireless extension of the JPEG 2000 standard formally known as JPWL is the newest international standard for still image compression. Different from all previous standards, this new standard was created specifically for wireless imaging applications. This paper examines the error resilience performance of the JPEG, JPEG 2000 and JPWL standards in combating multi-path and fading impairments in...
This paper analyzes the ergodic capacity in Rayeigh fading case and derives the signal-to-noise ratio (SNR) conditions for achieving the lower bound on ergodic capacity when nodes have different number of antennas, especially when the number of source antennas is larger than that of the destination's and the relay transmitter and receiver's. Then we verify it through simulations. Besides, simulation...
In this paper, we investigate the outage probability and bit error rate performance of the amplify-and forward relay network. The system model we consider has three nodes, with one antenna at the transmit end, one antenna at relay node, and multiple antennas at the receive end where maximal ratio combining is employed. In the Rayleigh fading channel, we derive closed-form upper and lower bounds of...
