Quadrature Demodulation of Binary Phase Shift Keyed Signals

摘要

A quadrature demodulation scheme for Binary Phase Shift Keyed (BPSK) signals is presented. Theory of operation of this demodulator and circuit details for its implementation are given. This technique is useful in systems designed for burst data application requiring fast acquisition such as Time Division Multiple Acces (TDMA), Random Access Descrete Address (RADA) communication systems using binary phase coded sequences for addressing.
