dc.description.abstract基于多用户检测原理,针对传统的Turbo码通过信道信息来获得信息住的信息,修正了带校验位的并行级联Turbo码的BCJR算法,通过多用户提供的先验信息来获得信息位和校验位的信息,使其能和低复杂度的多用户检测器匹配,从而进行信息迭代,达到了消除多用户干扰的目的。
dc.description.abstractIn traditional turbo decoding algorithm, it get information from the channel message without parity bits information. In this paper, we propose a modifying BCJR algorithm based on the turbo iterative multiuser detector principle witch includes system bits information and parity bits information from the multiuser detection to match the low-complexity SISO multiuser detector. The simulation results show its great performance.
