A novel M-ary multicarrier spread spectrum scheme based on wavelet packet is proposed, which can achieve a higher bit transfer rate under the restricted bandwidth condition. 将小波包理论与M元扩频技术相结合,提出基于小波包的M元多载波扩频系统可以在有限带宽内取得更高的信息传输速率。
The correlation properties of sequences have an important effect on multiple access interference and multi-path interference, and hence affect the bit error rate ( BER) and data transfer rate of systems to a large extent. 序列的相关性能直接影响到系统的多址干扰和多径干扰的大小,从而在很大程度上决定了系统的误码率性能和传输速率。
