π/2-BPSK in 5G NR — constellation, PAPR benefit, and mapping
What π/2-BPSK is in 5G NR uplink, how alternating BPSK constellations cut PAPR, the 3GPP mapping equation, and links to BPSK/QPSK and the BER tool.
Minimum Shift keying (MSK)
Constellation diagram – investigate phase transitions
The phase transition properties of the different variants of QPSK schemes and MSK, are easily investigated using constellation diagram. Let’s demonstrate how to plot the signal space constellations, for the various modulations used in the transmitter. Typically, in practical applications, the baseband modulated waveforms are passed through a pulse shaping filter for combating the phenomenon … Read more
