Abstract

We propose a new multi-user detection of slow frequency hopping multicarrier direct-sequence code division multiple access technique (multi-user detection of SFH/MC DS-CDMA). The frequency hopping pattern are controlled by asset of constant-weight code. Consequently, multirate communication can be implemented by selecting the correspondence set of constant-weight code. We assume the system operates in multipaths fading environment and a decorrelating receiver structure, The receiver has an explicit knowledge of the associated frequency-hopping (FH) patterns invoked. The system's performance is evaluated using Nakagami fading channels with numerical method. Furthermore the performance of the multi-user detection of SFH/MC DS-CDMA system is compared to the conventional Multi-user detection of direct-sequence code division multiple access system (multi-user detection of DS-CDMA).
慢跳频多载波DS-CDMA在中川衰落信道下的多用户检测性能分析
提出了一种新的慢跳频多载波直接序列码分多址多用户检测方法(SFH/MC DS-CDMA多用户检测)。跳频模式由等权码资产控制。因此,可以通过选择等权码的对应集来实现多速率通信。我们假设系统运行在多径衰落环境和去相关接收器结构中,接收器明确知道所调用的相关跳频(FH)模式。采用中神衰落信道对系统性能进行了数值评价。并将SFH/MC DS-CDMA系统的多用户检测性能与传统的直接序列码分多址系统的多用户检测(DS-CDMA的多用户检测)进行了比较。
