Qam psk

TīmeklisTherefore, 16-QAM may be considered better than 16-PSK for AWGN channels with similar spectral efficiency. However, the choice of modulation scheme also depends on other factors, such as the complexity of the receiver and the availability of power amplifiers that can handle the required signal bandwidth. TīmeklisIt is possible to combine ASK, FSK and PSK. One benefit of combining different modulation methods is to increase the number of symbols available. ... (QAM). QAM …
