| Abstract: | This paper introduces the principle of MSK modulation,presents a kind of algorithm about MSK digital modulation and demodulation,and designs the hardware framework which contains fast acquisition of spread spectrum signal by matching filter,carrier wave tracking and bit synchronization by dot metrix and cross metrix algorithms. Then it completes the simulation of this principle on Matlab,and is realized on DSP FPGA platform. |
