....under Grant ARODAAB19 00 1 0507. DESIGN METHODOLOGIES FOR ADAPTIVE AND MULTIMEDIA NETWORKS space time codes can significantly increase the rate of reliable communications, allowing the separation of multiple users transmitting at the same time, using the same modulation and access protocol [3]. Geographical locations of users provide network diversities in signal propagation. This has recently been exploited for signal processingbased collision resolution [4] Also related is spread Aloha [5] where, by subsampling the output of the matched filter, a receiver can separate signals from ....

Employing transmitting and receiving antenna arrays with properly designed space time codes can significantly increase the rate of reliable communications, allowing the separation of multiple users transmitting at the same time, using the same modulation and access protocol [3]. Geographical locations of users provide network diversities in signal propagation. This has recently been exploited for signal processingbased collision resolution [4, 17] Also related is spread Aloha [5] where, by subsampling the output of the matched filter, a receiver can separate signals ....

....according to the movement of a mobile terminal. Thus, multipath interference (MPI) also significantly degrades the link performance. To suppress these sources of interference and to increase the reverse link capacity, adaptive antenna array beam forming (AAA BF) is under extensive investigation [2], 3] We recently proposed the coherent adaptive antenna array diversity receiver (CAAAD) 4] in which the receiver antenna weights are adaptively updated so that the signal to interference power ratio (SIR, note that we assume that the background noise is included in the interference) after Rake ....

....or a rake receiver. Meanwhile, spatial signal processing reduces the CCI using a smart antenna. When spatial signal processing is combined with temporal signal processing, the space time processing can further improve the impairments to result in a higher network capacity, coverage, and quality [1][2] 3] A smart antenna not only suppresses interferences, but also combats multipath fading by combining the multiple antenna signals. The smart antenna technique has been considered mostly for base stations [4] because of its high system complexity and large power consumption. In addition, two ....

....only combats multipath fading, but also suppresses interference signals. When spatial signal processing achieved through smart antenna is combined with temporal signal processing, the space time processing can repair signal impairments to result in a higher network capacity, coverage, and quality [1] [3] When compared with the conventional single antenna system, a smart antenna system requires additional antennas and circuitry to process multiple antenna signals. The additional antennas and circuitry result in higher cost and more power consumption. Smart antenna techniques have been ....
