Patent ID: 6940930

Claim:
A method for automatic I/Q balancing for packets of an incoming signal, comprising: resolving an on-line incoming signal into I and Q signals; computing packet-fixed correction coefficients from said I and Q signals during a measurement section for a packet; correcting at least one of I/Q gain and I/Q phase of said I and Q signals with said packet-fixed correction coefficients for providing corrected said I and Q signals for said packet; delaying said I and Q signals by at least said measurement section; and wherein the step of correcting includes correcting said at least one of said I/Q gain and said I/Q phase of said delayed I and Q signals with said packet-fixed correction coefficients for providing said corrected I and Q signals; detecting pre-delay averages for said I and Q signals for a time period not greater than said measurement section before the step of delaying said I and Q signals; and using said pre-delay averages for reducing DC offset from said delayed I and Q signals before the step of correcting said I and Q signals.
