SSB PLL Demodulator Based on SDR
|
Abstract:
The SSB modulation technique has many advantages of narrow band, high SNR, low emission power, however the demodulation is complex, According to Weawa method, COSTAS-PLL, dual linear transform, a new SSB PLL demodulator based on SDR is brought out. The demodulator which runs on TMS320C6203 is capable to process real-time 160kHz signal and capture 8kHz frequency deviation.
