| Abstract: | Three schemes of combination of packet scheduling(PS) and adaptive antenna arrays(AAA) for OFDM systems are proposed and compared in this paper.They are:(1) PS selects user(s),AAA serves it/them;(2) PS and AAA select user(s),AAA serves it/them;(3) AAA selects user(s),AAA serves it/them.From simulation results,AAA can increase the system performance compared with single antenna transmission.And(2) and(3) are better than(1). |
