Research on TFCI Decoding Algorithm Based on Fix Gain Matrix

在TD-SCDMA下行链路的物理层信令中,如何提高"传输格式组合指示(TFCI)"译码的正确率,成为众多改进算法的焦点,文中基于传输业务组合和高层配置参数相结合,提出了一种基于修正增益矩阵的译码方法,该方法非常易于用高速数字信号处理实现。仿真表明,在相同信道环境下,新算法比原算法的译码性能有了明显改善。

How to improve the decoding capability of TFCI in the Physical Signaling of TD-SCDMA has become the focus of many modified decoding algorithms. In this paper, a new decoding algorithm based on modified gain matrix is proposed upon parameters configured by high level indication, and it can be easily implemented on the DSP platform. Both theory and simulation results show that the decoding capability is greatly improved.
