What is the bandwidth of M-ary PSK?

In a M-ary PSK digital communication system, it is required to transmit the data with 80 Mbps bit rate within maximum allowable channel bandwidth of 16 Mhz.

What is M-ary modulation?

An M-ary transmission is a type of digital modulation where instead of transmitting one bit at a time, two or more bits are transmitted simultaneously. This type of transmission results in reduced channel bandwidth. However, sometimes, two or more quadrature carriers are used for modulation.

Which modulation scheme occupies more bandwidth?

10. Which modulation requires more bandwidth? Explanation: BPSK requires more bandwidth than the other modulation techniques for the given level of spectral density.

Which modulation scheme has minimum bandwidth?

Linear modulation techniques, including all forms of quadrature-amplitude modulation (QAM) and phase-shift-keying (PSK), use less bandwidth than nonlinear techniques, including various forms of frequency/minimum-shift-keying (FSK and MSK).
