Title: Digital quadrature phase modulator-demodulator for telecommunications - has pairs of digital filters applying filtered signal or inverse signal to subtractor obtaining real and imaginary output components
Inventor: YONG GUO XIAO
IPC: H04L27/38
Filed: 1992-05-15
Abstract: The quadrature phase modulated signal is applied to a time demultiplexer (231B),  split into four time segments and applied to filters (234B, 235B, 236B, 237B). Each filter samples the incoming signal at four times the carrier frequency, and filters out the carrier frequency. The filters are divided in pairs,  one pair supplying the signal and its inverse to a subtractor (241B) to produce the real vector output, and the other supplying the imaginary component and inverse imaginary component to a subtractor (240B) to produce the imaginary output. Thus the phase of the output signal can be found. ADVANTAGE - Overcomes problems with two separate paths with analogue system, which needs fine tuning. Practical solution with realisable clock frequency.
