In this paper, the authors describes about BPSK (Binary Phase Shift Keying) demodulation using cost as loop and implementing on a DSP (Digital Signal Processor) kit. The demodulation process can be divided into three major subsections. First, since the incoming waveform is suppressed carrier in nature, coherent detection is required. The methods by which a phase-coherent carrier is derived from the incoming signal are termed carrier recovery. Next, the raw data are obtained by coherent multiplication, and used to derive clock-synchronization information.
