gsm adjacent channel
Hi guys,
I met a problem with adjacent channel rejection failed in GMSK modulation
for EDGE mode while pass for GSM mode. Many points that I would check, but
one of them would be only adjustable by me, RF system worker, is
to change AGC/Front-end gain plan.
I'm wandering this way would made noise difference by lowering front-end gain
while making PGA cascaded gain higher ?
Or any other points that you can recommend ?
Thanks!
