| 摘 要： | 文章分析了非连续导频情况下CDMA2000反向信道结构，针对CDMA2000反向信道中导频信道与功控子信道时分复用情况，研究了四种信道估计方法，分别是重复使用、判断校正及其改进方法、最小二乘插值。最后用COSSAP软件对这四种方法的性能进行了比较，仿真结果表明改进的判别校正和最小二乘插值方法能有效的估计出插入功控比特导频情况下的信道参数。 |
| 关 键 词： | CDMA2000 时分导频 信道估计 |

| Abstract: | In CDMA2000 standard, the pilot channel is time-multiplexed with power control bits and is not continuous. Four channel estimation approaches such as repeat using, adjusting with estimation (with amelioration) and linear interpolation are studied for this case. The average BER performance of the proposed ameliorated adjusting with estimation approach is near that of the continuous pilot channel and the proposed linear interpolation even exceeds that of the continuous pilot channel. |
| Keywords: | CDMA2000 time-multiplex pilot channel estimation |
