Estimated Frequency and Phase Rotation Principles and Their Realization in ABPSK
HU Tie-qiao · 2006
When ABPSK receiver uses diffenence demodulation,frequency difference will unavoidably exist,thus seriously affecting the performance of demodulator.The paper expounds the principles of estimated frequency and phase rotating and presents the flow diagram of how to use TMS320c 25 to realize estimated frequency.In addition,with the 600bps T channel as an example the paper analyses the functions of estimated frequency and phase rotation in detail.
