Amplitude shift keying, Frequency Shift Keying, Binary Phase Shift Keying: Generation and Detection
Why is coherent detection preferred over non-coherent detection in PSK systems under AWGN?
Consider a binary PSK system. What is the minimum Euclidean distance between symbols if the signal power is normalized to 1?
In digital modulation, what factor primarily determines the bandwidth efficiency of a scheme?
In BPSK, what is the theoretical bit error rate (BER) under AWGN with coherent detection and Eb/N0 = 10 dB?
In M-ary PSK, what is the primary trade-off when increasing the value of M?
How does Gray coding benefit digital modulation schemes?
For a signal with bit rate R and modulation with k bits per symbol, what is the symbol rate?
Which digital modulation scheme is most robust to noise in an AWGN channel?
A digital system transmits 16-QAM symbols at 1 Msymbol/s. What is the bit rate of the system?
In a binary ASK system with coherent detection, what kind of filter maximizes the SNR at the detector?
