Wireless receiver for removing direct current offset component
摘要:
A wireless receiver includes a hardware (HW) block, a converter block and a digital signal processor (DSP). The HW block receives a wireless signal having a first DC Offset Component (DCOC), removes a portion of the first DCOC to produce a residual DCOC centered at DC, and generates parameters that estimate the residual DCOC. The converter block is coupled to the HW block and receives the residual DCOC centered at DC and converts it to a residual DCOC centered at IF. The DSP is coupled to the HW block and the converter block and receives the residual DCOC centered at IF from the converter block and the parameters from the HW block, and uses the parameters to eliminate the residual DCOC, and generate a baseband signal that is substantially free of the first DCOC and the residual DCOC.
