why is BPSK better than BFSK in presence of noise

Answer Posted / parth gupta

Although, it is observed through simulations that BPSK system
gives better bit error performance as compared to BFSK systems. But BFSK proves better in adjacent channel
interference conditions. Also mathematical derivations prove that BFSK approaches MSK (Minimum Shift
Keying) and MSK is the most suitable digital modulation scheme for power limited systems.
