| 摘要: |
| 在分析同步多载波CDMA系统基带发射、接收模型和多径衰落信道模型的基础上,提出一种新颖的误码率分析方法。对系统在瑞利(Rayleigh)衰落信道中的误码性能进行了理论研究,得到了BPSK调制条件下的系统误码率表达式。数值分析结果表明:多载波CDMA在无线宽带数据传输中性能大大优于CDMA,具有良好的应用前景。 |

| Abstract: |
| On the basis of modeling synchronous MC-CDMA system and multi-path fading channel, a novel and convenient analyzing method for bit error ratio is proposed. The performance of bit error for MC-CDMA in Rayleigh fading channel is discussed, then the expression of BER is obtained. The numerical results of simulation show that the ability of MC-CDMA for wireless broadband data transmission is much better than CDMA, therefore having good perspective for business application. |
