Capacity/modulation tradeoffs in going from 64 QAM to 256 QAM

IEEE International Conference on Communications, Including Supercomm Technical Sessions, 1990
Summary form only given. Increasing the modulation complexity permits significant improvements in bandwidth efficiency. However, the higher level modulation schemes must include additional countermeasures to minimize increased susceptibility to dispersion, loss of threshold, further transmitter power backoff, and increased interference susceptibility. >

Modulátor QAM

Náplní práce je zvážit možné způsoby realizací vícestavových modulátorů pro vytvoření laboratorního přípravku. Přípravek bude názorně ukazovat signály, které se podílí na vytváření modulací QAM. Návrh přípravku v práci obsahuje teoretický návrh schématu i samotné vyhotovení funkčního prototypu.
