Abstract:

There are many implementations of phase modulation,among which the most commonly used is orthogonal modulation.A new design of phase modulation by using microwave phase shifting is presented,by which 2,4,8,16,32 and 64 phase modulations are implemented.Tests show the phase shifting error of the new design is lower than 1.2°  with as good a bit error ratio (BER) as that of the orthogonal modulation.Besides,the new design does not require the digital to analog converter (DAC),orthogonal modulator and mixer that are necessary in the general applied orthogonal modulation,thus simplifying the system and reducing the cost.

Key words: micro-strip;phase shifter;BER;phase modulation;orthogonal modulation
