| Abstract: | The authors briefly introduced the definition and characteristic of spatial diversity,and presented a detailed description of transmit diversity which employed STBC,and received diversity which employed MRC,compared the different impact of the two methods on improving the throughput of OFDM based WLANs through simulation.The result showed that receive diversity can achieve even higher throughput than that of transmit diversity,of course,both of them would improve the throughput of OFDM based WLANs |
