摘要: GSM baseband receiver arrangement using digital signal processing is disclosed. The comprises two channel for inphase (I in ) and quadrature (Q components of the received signal. DC offset each separately estimated by accumulating samples from outputs second filter stages M 1 2 dividing result 64. then negated applied to controls I . This stage process ensures that majority removed prior variable gain, residual before frequency shifting. Applying correction shifting annulled any subsequent shift.
