| 摘 要： | 对M带小波的基本理论及其提升格式进行了较深入研究，基于提升理论提出了一种新的多载波调制系统——M带小波提升多载波调制（LWMT）系统. 通过在多径信道、加性高斯白噪声（AWGN）信道及存在脉冲干扰情况下对其误比特率(BER)进行详细的分析及系统仿真，得到了基于提升的M带小波多载波调制系统在多径信道下及存在脉冲干扰时其系统性能优于传统的正交频分复用（OFDM）系统，而在AWGN下其性能与传统OFDM系统相当的结果.

| Abstract: | A new multicarrier modulation system M band lifting wavelet multicarrier modulation(LWMT) system was proposed based on M band wavelet theory and its lifting scheme.Through analyzing bit error rate(BER) and simulated the system under additive white Gaussian noise(AWGN) channel and fading channel,the result shows that: in fading channel the performance of LWMT system is better than orthogonal frequency division multiplexing(OFDM) system.In AWGN channel the performance of LWMT system is same as OFDM system but LWMT system performance is superior to OFDM system in the anti-narrow interference. |
