摘要 分析了用有限几何中的点线构造而成的LDPC码的结构特征,同时分析了它的译码方 法,并比较了三种不同构造的LDPC码在同一种译码方法下的误比特率．最后把性能良好的 LDPC应用到CDMA通信系统中,从而提高了CDMA通信系统的容量． The construction and characteristic of the LDPC codes, which are constructed by the points and lines of finite geometries, are analyzed in this paper. At the same time, its decoding methods are analyzed. What＇s more, the bit error rates of three different construction LDPC codes, which are made with the same decoding method, are compared. Finally, the well-performing LDPC codes are applied to CDMA communication systems with the result that the capacity of the CDMA systems is increased.
