Consider the 16-psk constellation and the rectangular, Ask an Expert

Engineering

Consider the 16-PSK constellation and the rectangular 16-QAM constellation shown in Fig. P7.1. We have two transmitters, each using one of these constellations. In order to have approximately the same performance (error rates) at the receiver, what should be the difference (in decibels) in the transmitted power for the two transmitters? What are the advantages and disadvantages of 16-PSK versus 16-QAM modems?
