摘要
主要讨论ＨＳＰ５０２１５内部各种功能模块，分析其结构，用ＭＡＴＬＡＢ对其进行功能仿真，实现ＢＰＳＫ、ＱＰＳＫ、ＯＱＰＳＫ、ＭＳＫ、ＧＭＳＫ、π／４—ＱＰＳＫ、ＱＡＭ、ＡＭ、ＦＭ等调制，绘出波形和频谱。
This paper is mainly concerned with the function blocks of HSP50215 and the structure inside. Then we give the function simulation of HSP50215 using MATLAB. It includes the modulations of BPSK, QPSK, OQPSK, MSK, GMSK, π/4-QPSK, QAM, AM and FM. Final we give out their output waves and frequency spectrums.
