-SCDMA picocell低代价联合检测的实现
Low Complexity Implementation of Joint Detection for TD-SCDMA picocell
联合检测可以同时消除CDMA系统中的码间干扰（ISI）和多址干扰（MAI）。本文对基于Cholesky分解的迫零块线性均衡（ZF-BLE）的联合检测算法进行分析，给出了适用于picocell条件下联合检测的简化算法，并给出一种低代价联合检测的实现方案。通过计算和仿真表明，该方案可以在保证联合检测性能的同时极大的减少计算量，可以用于低成本的picocell基站的实现。
he joint detection algorithm can eliminate the Inter Symbol Interfere (ISI) and Multiply Access Interfere (MAI) at the same time. The Zero Force Block Equalization (ZF-BLE) based on Cholesky decomposition algorithm is analyzed, and a new implementation of joint detection is proposed in this paper which is simplified and fit for picocell. It is illustrated by calculation and simulation that this proposal can greatly cut down the computation and complexity while maintaining the performance and it can be used in a cost-reasonable picocell base station.
