摘要: The transmission capacity of an ad-hoc network is the maximum density active transmitters per unit area, given outage constraint at each receiver for a fixed rate transmission. Most prior work on finding networks has focused only one-way communication where source communicates with destination and no data sent from to source. In practice, however, two-way or bidirectional required support control functions like packet acknowledgements channel feedback. This paper extends concept wireless by incorporating different requirements in both directions. Tight upper lower bounds are derived frequency division duplexing. obtained used derive optimal solution bandwidth allocation that maximizes capacity, which shown perform better than allocating proportional desired Using proposed framework, bound transmit beamforming using limited feedback as function number bits allocated
