摘要
为了有效克服无线通信中普遍存在的码间干扰效应,提出一种新的QAM调制方式,即蜂窝型(非正方形)16QAM。用QAM系统进行的计算机仿真结果表明基于蜂窝型16QAM比基于正方形16QAM的常数模盲均衡算法(CMA)更具抗干扰能力,收敛速度更快,验证了蜂窝型16QAM的性能。
In order to effectively overcome the widely existing ISI （inter-symbol interference） in wireless communication, a new QAM modulation was proposed in this paper, which is honeycomb （non-square） 16QAM. Computer simulation is implemented with QAM system,The results has shows that the Constant Modulus Algorithm （CMA） based on the honeycomb 16QAM gains more anti-interference and faster convergence than based on the square 16QAM.
