DPSK (Differential Phase Shift Keying) is more robust against phase fluctuations during transmission compared to PSK (Phase Shift Keying). It eliminates the need for a phase reference, making it more suitable for noisy channels. Additionally, DPSK can provide better error performance in certain scenarios compared to PSK.

Advantages of psk over fsk and ask?
PSK (Phase Shift Keying) is advantageous over FSK (Frequency Shift Keying) and ASK (Amplitude Shift Keying) because it provides higher data rates and better spectral efficiency. PSK is less susceptible to noise and interference since phase changes are more discernible than frequency or amplitude changes. PSK also allows for easier implementation in digital communication systems.

When a test allows a person from one particular background to have an unfair advantage over persons from other backgrounds it is called?
When a test allows a person from one particular background to have an unfair advantage over persons from other backgrounds, it is called bias. Bias can manifest in various forms, such as cultural bias, language bias, or socioeconomic bias, which can result in inequities in test performance based on an individual's background.
What is the difference between theory of absolute advantage and a theory of comparative advantage?
The theory of absolute advantage states that a country should produce goods that it can produce more efficiently than other countries. On the other hand, the theory of comparative advantage argues that a country should specialize in producing goods that it can produce at a lower opportunity cost compared to other countries, even if it does not have an absolute advantage in that good.

Difference between absolute PSK and differential PSK?
In abs. PSK only instant phase for the incoming bits are considered. For DPSK, the difference between previous phase and the present phase is considered. Example: If BPSK is used, then for 0 if phase if pi and for 1 it is 0, then for abs. BPSK the phase states for the bit stream 1010 will be 0,pi,0,pi for DPSK, we assume initial phase is zero and a rule that , if incoming bit is zero, then phase difference is 0 and if it is 1 then, phase difference is pi. So, phase difference will be--pi,0,pi,0 Instant phase will be, pi,pi,0,0....Easy!!

What is the advantage of qam over ask and psk?
PSK and QAM modulation have two advantages over ASK: *They are not as susceptible to noise. *Each signal change can represent more than one bit PSK Disadvantage more complex signal detection / recovery process, than in ASK and FSK QAM advantage: · data rate = 2 bits per bit-interval! · higher data rate than in PSK (2 bits per bit interval), while bandwidth occupancy remains the same • 4-PSK can easily be extended to 8-PSK, i.e. n-PSK • however, higher rate PSK schemes are limited by the ability of equipment to distinguish small differences in phase uses "two-dimensional" signaling • original information stream is split into two sequences that consist of odd and even symbols · PSK modulators are often designed using the QAM principle, but are not considered as QAM since the amplitude of the modulated carrier signal is constant. QAM is used extensively as a modulation scheme for digital telecommunication systems. Arbitrarily high spectral efficiencies can be achieved with QAM by setting a suitable constellation size, limited only by the noise level and linearity of the communications channel. · Noise immunity of QAM is very high. · QAM is best suitable for high bit rates. · Low error probability. · Baud rate is half the bit rate therefore more effective utilization of the available bandwidth of the transmission channel.
