-
摘要: 本文把Malvar子波变换应用于多载波调制(MCM)系统,提出了对信道进行不等带宽分配,克服多个单音(窄带)干扰的思想,有效地提高了信道的利用率和系统的稳定性。Abstract: In this paper, Malvar wavelet transform is implemented in MCM (Multicarrier Modulation) system. It is proposed that assigning the bandwidth nonuniformly using Malvar wavelet transforming is to combat with the multi-tone noises existing simultaneously in MCM system and to improve the efficiency of utilizing the bandwidth.
