Patent ID: 7839314

Claim:
A satellite radio receiver, the receiver being adapted to remove I/Q mismatches in a received navigation signal and comprising: resolving means for resolving the received navigation signal into I and Q signal components, and a demixing stage arranged to receive as input signals said signal components for demixing said signal components from unwanted signals, wherein said demixing stage comprises a first input coupled through a first signal path that includes first subtraction means to a first output, a second input coupled through a second signal path that includes second subtraction means to a second output, a first adaptive filter being coupled from said first signal path to said second signal path, and a second adaptive filter being coupled from said second to said first signal path, and means for updating the coefficients of said adaptive filters by the outputs of the demixing stage, the outputs of the demixing stage representing IQ-mismatch corrected signals.
