| 传统联合检测技术算法复杂度高，不利于TD-SCDMA下行链路基带接收芯片的设计。本文提出了一种新的分决联合检测算法，将需要运算的矩阵进行分决处理，以降低运算量。在理论分析的基础上，建立下行链路仿真模型，通过分析分决数目对系统性能以及运算复杂度的影响，可以证明分决技术显著降低了下行链路接收机的运算复杂度。 |

| Abstract: |
| Traditional joint detection algorithm is complicated when used in TD-SCDMA downlink. A new joint detection algorithm based on block is developed. Matrix is divided into several blocks to decrease the complexity. Based on theoretical analysis, downlink system model is constructed and simulated by computer. The effect of the number of blocks on system performance and operation complexity is analyzed in the simulation and the complexity of the algorithm can be greatly reduced. |
