【摘要】 讨论了16QAM调制时应用不同类型和参数的滤波器对系统性能的影响.针对16QAM的特点,采用了存储波形累加求和法来代替一般的滤波成形,提高了调制速度.并利用其相位对称的特点将波形存储表压缩为原容量的1/4,有效地节约了存储空间.更多还原

【Abstract】 This paper discussed the 16QAM system performance using different kinds of pulse shaping and matched filters with different factors.Then to improve the real time quality the general pulse shape method is replaced with the wave shape storage and adding method.By taking advantage of symmetry to compress the storage,much storage capacity is saved.更多还原
