The STBC Technology of Tiny Area and Slight Small Area Applies in Ad Hoc Networks

This paper presents a algorithm of Ad Hoc channel distribution when then one-hop covered area is a tiny area or slight small area. Then it researches the Alamouti space-time encoding scheme and Alamouti space-time decoding scheme. In Addition, it also researches the agreement of STBC switching into Ad Hoc network CSMA/TDCA. And it presents two improvement plans to avoid phenomenon of competing and conflicting. The improvement plans will not only fully utilize the resources of the slot, but also effectively avoid interference, thereby enhance the operational efficiency and the quality of the entire network. Finally, the STBC technology of tiny area and slight small area Applies in Ad Hoc Networks is simulated. The simulation results illustrate that, the technology has positive effort on bit-error-rate reducing.
