| Abstract: | In this paper, we begin with some existing technologies improving capability of BWA system, analyzing some resolvents of overcoming communication defects, and finally summarize that the key of improving the capacity of BWA system is to e, thance the utilization ratio of existing bandwidth and the tolerance to the frame error of wireless channel. And then, we steeply adopt multi - ARQ to guarantee the throughput and the good supports to the services of real - time and non real - time in BWA system. |
