| Research Abstract |
In this project, we have successfully estimate and exploit the source correlation in distributed cooperative wireless network to achieve close-limit Slepian-Wolf multiple access channel (SW-MAC) rate region theoretical performance. We found that point very close to (1,1) mutual information of the extrinsic information transfer (EXIT) chart can be reached easily by using memory-1 rate-1 doped accumulator, which make the error-floor invisible (below 10^-7). For broadband transmission, our multiple input multiple output (MIMO) turbo equalizer work very efficiently to approach a performance only about 1 dB away from the theoretical MIMO/SW-MAC limit. Our system also work well even when very simple memory-1 convolutional codes are used. The potential applications are for power limited wireless multi-hops and ad-hoc wireless network, sensor/monitoring networks, where sensor collect the correlated data and transmit it to a common destination (fusion center) with higher spectrum efficiency. The main publications of the project are on IEEE Transaction on Signal Processing, IEEE Communication Letters and some major IEEE international conferences.
