摘要:
为利于选择合适的调制参数,尽可能提高最小欧式距离,改善功率谱密度,降低译码复杂度,基于Laurent分解,将球形译码方法应用于连续相位调制信号检测中。针对3种典型脉冲函数的连续相位调制信号,在不同调制参数情况下,比较其功率谱密度、最小欧氏距离和译码率等性能之间的关系,并进行了仿真验证。研究结果表明,GMSK的功率谱密度最好,旁瓣衰减更大;无论矩形脉冲还是升余弦脉冲,调制指数05时都比调制指数075时的最小欧氏距离高,误码率更低。
Abstract:
To determine the most suitable modulation parameters so as to maximize the minimal Euclidean distance(MED),improve the power spectrum density(PSD),and reduce the complexity of decoding,sphere decoding(SD) algorithm was employed in detection of CPM signals based on Laurent decomposition.CPM signals with three typical pulseshaping functions were then studied for the relationship among PSD,MED,and bit error rate(BER) in terms of various parameters of modulation,and simulations conducted to verify the analysis.The results show that the PSD for GMSK is the best for its fastest side lobe attenuation and the modulation index at 05 for REC and RC are both higher than the MED of 07,which means lower BER.
