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

ABSTRACT "o.g}Pv  
This paper presents a new I/Q regeneration technique 8#&axg?a  
for direct receivers which employ quadrature #\X="'/  
modulation. The technique is based on the property }"CX`  
that I/Q components of the received signal are uncorrelated, fF*{\  
and is applicable to any quadrature modulation. vsL)E:0  
A K-band 5-port junction based direct receiver {D9m>B3"{  
prototype has been developed which supports data rfVHPMD0  
rate of 89.472 Mbps with QPSK modulation. The biterror- Fv(1A_~IS  
rate performance has been .. I"1H]@"=

very much !

thanks a lot b:M1P&R
