[射频]I,Q CHANNEL REGENERATION IN 5 PORT JUNCTION BASED DIRECT RECEIVERS

ABSTRACT ]MjQr0&M  
This paper presents a new I/Q regeneration technique  m9My  
for direct receivers which employ quadrature ${"+bWG2G!  
modulation. The technique is based on the property B%HG7  
that I/Q components of the received signal are uncorrelated, 5a moK7  
and is applicable to any quadrature modulation. Xy{\>}i]N  
A K-band 5-port junction based direct receiver xL,;(F\^  
prototype has been developed which supports data zZ3Ko3L%g_  
rate of 89.472 Mbps with QPSK modulation. The biterror- YGVj$\  
rate performance has been .. GC(:}e|
