| 摘 要： | 两用户分层Alamouti码编码的多入多出系统采用最大似然译码能获得满分集增益,但复杂度较高,若利用复杂度较低的部分干扰相消(PIC)和串行干扰相消(SIC)辅助的PIC-SIC分组译码则会损失分集增益,为此提出一种编码方案,并证明此方案在接收天线数为N时利用PIC-SIC分组译码能获得满分集增益2N.仿真结果表明,新编码方案相对于分层Alamouti码能获得更优的误码率性能和更高的分集增益.

| Abstract: | For a two-user layered Alamouti-coded multiple-input multiple-output(MIMO)system,the complexity of the maximum-likelihood decoding is high while full diversity is achieved.Using low-complexity partial interference cancellation(PIC) group decoding and its combination with successive interference cancellation(PIC-SIC) group decoding,one space-time coding scheme is proposed.Full diversity gain is proved to be achieved with the PIC-SIC group decoding by the analytical derivation of the symbol error rate.Simulation confirms the derivation and its better bit-error rate performance over layered with the PIC and PIC-SIC group decoding. |
