What is FB in BPSK?

If fb = , then for BPSK, the maximum frequency in the baseband signal will be fb as shown in figure 8.12. In this figure, the main lobe is centred around carrier frequency fc and extends from fc – fb to fc + fb. Therefore Bandwidth of BPSK signal will be, BW = Highest frequency — Lowest frequency in the main lobe.

How is BPSK signal generated?

Convert unipolar to bipolar in the databits. Modulate the bipolar bits with Binary Phase Shift Keying (BPSK). Multiply the baseband BPSK with a carrier fc = 100 Hz. The modulated BPSK signals will be transmitted through a Noiseless channel.

What is BPSK spectrum?

Convolution of any spectrum with a frequency impulse centers this spectrum about the frequency of the impulse. Therefore, the BPSK spec- trum is the spectrum of the baseband symbols, centered about the carrier frequency. The spectrum of the baseband symbols is rather complicated.
