- complete orthogonal sequence 完全正交序列
- Like multicarrier modulation, the high rate data transmitted at first by serial-to-parallel convert, then the low rate data streams are spreaded spectrum by a set of orthogonal sequence. 相似于多载波调制,传输的高数据率首先进行串-并转换,然后对转换后的低数据流用正交序列进行扩频调制。
- In direct sequence spread spectrum multiple access (DS-CDMA) communication system, in order to transmit high rate data, a orthogonal sequence multicode CDMA system (called OMC-CDMA) is proposed. 在直接序列扩频通信(DS-CDMA)系统中,为了有效地实现用户高数据率的传输,本文提出了一种正交扩频多码CDMA系统(称为OMC-CDMA)。
- The Walsh function system is a complete orthogonal system, it constructs the Abelian group. Hence, both the differential equation and the integral equation could be solved by using the Walsh function. 沃尔什函数系是完备的正交系;且构成阿贝尔群;因此可用沃尔什函数解微分、积分方程.
- Mutually orthogonal sequence sets 相互正交序列集
- DPSS are set of indexlimited orthogonal sequences, which have maximum spectral energy in the frequency range. 在众多的正交序列中,DPSS在设定的频率范围内具有最大的频谱能量。
- complete orthogonal function system 完备正交函数系
- In the CDMA wireless communications system , multi-access interference and near-far effect exist because spread codes between users are not completely orthogonal along with different users random accessing, regular filter can not overcome these questions. 码分多址系统中,不同用户的随机接入,使得用户之间扩频码不完全正交,进而产生了多址干扰(Multi-access interference,MAI)和远近效应(Near-far effect,NFE)等问题,常规的匹配滤波器无法克服这些问题。
- In this paper, the shift sequences of polyphase orthogonal sequences are distributed to different user and the ideal auto-correlation properties are utilized for CDMA communication. 本文提出将同一多相正交序列的各个具有不同初始相位的移位序列分配给不同用户作为地址码,利用多相正交序列理想的自相关特性进行码分多址通信。
