【摘要】 在STBC-OFDM系统的基础上介绍了SFBC-OFDM系统的原理、编译码方案,并通过仿真做出了SFBC-OFDM系统在快衰落信道下的性能,同时与STBC-OFDM系统的性能进行比较。结果表明:SFBC-OFDM系统在室内环境即时间延迟缓慢的情况下性能与STBC-OFDM基本上达到一致,在室外环境快衰落情况下性能要比STBC-OFDM系统要好。更多还原

【Abstract】 The principle of STBC-OFDM system and scheme of coded and decoded are introduced based on the STBC-OFDM system in this paper.By the simulation, the performance of the SFBC-OFDM systems in fast fading channels is obtained.Compared with the performance of STBC-OFDM system,the result indicates that the performances of SFBC-OFDM system in indoor environment: time delays are slow,are consistent basically with the performances of STBC-OFDM,but in outdoor environment,the performance of fast fading is better than that of STBC-OFDM system.更多还原
