To implement coherent detection, a local oscillator (LO) that is exactly synchronized to the carrier must be provided at the receiver. A BPSK signal is a double sideband suppressed carrier (DSBSC) type of signal e(t) = p(t) cosω0t, and therefore, the carrier is not directly available in the BPSK signal. …
