Where does the process of combining the carrier signal and the baseband signal into one occur?

The process of mixing a baseband signal onto a carrier frequency is called upconversion, and is performed in the radio transmitter.

What is equation for BPSK modulation?

ADVANTAGES OF BPSK:- BPSK. modulation technique is a technique that offers several advantages over other modulation techniques that is it has the simplest of the system design, and it has power efficiency to be optimum. signal is –b(t) √2P cos(2πfct+θ) then the squared signal remains same.

What is baseband signal and carrier signal?

1. Original (“baseband”) information signal - frequency is too low to transmit efficiently. 2. Higher frequency (“carrier”) signal - we can transmit this efficiently, so we use it to carry our information.

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.
