Abstract
The most serious problem faced in zero-intermediate frequency (IF) receiver is DC-offset. DC-offset is caused by leakage of the local oscillator (LO) into the down converter input. The receiver performance is significantly degraded due to DC-offset. This paper illustrate, analyze, simulate and compare two digital signal processing (DSP) algorithms which remove this residual DC-offset. In the analysis, the settling time, maximum fluctuation and variance of the two DC estimators were derived.
