Abstract (en)
[origin: WO2007096800A2] A direct down conversion receiver (19) has an imbalance compensation parameter determining stage (20) and a phase and amplitude imbalance compensation stage (21). The determining stage (20) is connected to receive I and Q signals I'(t), Q'(t) output from I and Q paths (5, 6) of the receiver (19). The determining stage (20) determines imbalance compensation parameters g <SUB>1</SUB>
