| 摘 要： | 针对基于小波包变换的多载波通信系统的实现问题，提出了一种完整的基于小波包变换的多载波通信系统的实现方案．该方案由内外编码、小波包调制解调、信道估计及均衡、同步等部分组成，其基带部分（内外编码、交织、小波包调制解调）已在高速DSP上编程运行，并在TMS320C6701EVM板上进行了仿真测试．研究结果表明了该方案的可行性，由于基于小波包变换的多载波调制（WPT-MCM）较之正交频分复用（OFDM）有较多优势，本方案在高速数据传输领域及未来移动通信中具有良好的应用前景．

| Abstract: | The implementation of wavelet packet transform-based multicarrier communication system is investi-gated, and an integrated scheme of wavelet packet transform-based multicarrier communication system is pro-posed, which is composed of inner coding and outer coding, wavelet packet modem, channel estimation and equalization, synchronization, etc. Programmes of the scheme's baseband part, which includes inner coding and outer coding, interleaving and wavelet packet modem, were run on high-speed DSP chip. Simulation tests were also carried out on TMS320C6701 EVM to validate the feasibility of the scheme. As wavelet packet trans-form-based multicarrier modulation (WPT-MCM) has advantages over orthogonal frequency-division multiplexing (OFDM) , the proposed scheme has a bright application prospect in the fields of high-speed data transport and future mobile communication. |
