WebApr 20, 2024 · 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. At the receiver side demodulate the received signal by multiplying it with a carrier and passing it through a Low Pass Filter (LPF). WebApr 8, 2010 · Binary Phase Shift Keying (BPSK) is a two phase modulation scheme, where the 0’s and 1’s in a binary message are represented by two different phase states in the carrier signal: θ = 0∘ θ = 0 ∘ for binary 1 and θ = 180∘ θ = 180 ∘ for binary 0. In digital modulation techniques, a set of basis functions are chosen for a particular ...
