Specifications
• For applications where higher data throughputs are needed the additional increase in spectrum ef-
ficiency can be gained by D8PSK and 16-DEQAM modulation formats. However, compared to π/4-
DQPSK, an increase in overall communication efficiency cannot be expected, while there is the in-
evitable penalty in power efficiency characteristic.
