摘要
在无线通信中,由于信道存在有干扰和衰落,所以必须对信号进行信道编码以提高信噪比,特别在高速无线通信中更为重要。信道编码的方式有很多,该文对涡轮乘积码(TPC)的基本原理及其性能进行了分析,并根据实际工作的需要在FPGA上构建了一个实际的信道编码应用系统。仿真表明,TPC系统的强纠错能力和编码速率的灵活性非常适用于宽带无线通信。
Noise and fading character inherently exist in the wireless channel. It is, therefore, necessary to increase the SNR through channel coding, which is especially important in high speed wireless communication. There are many schemes of channel coding. This paper analyzes the basic principle of Turbo Product Code and its performance. A channel coding application system is designed with FPGA on the basis of practical needs. The results of simulation indicate that ability of TPC system to correct errors and the flexibility of code rate are applicable to wide band wireless communication.
