Method and apparatus for compensating DC level in an adaptive radio receiver

A method for operating a radio frequency RF receiver, comprising:

• changing a status of a component block in a manner expected to induce a DC offset in a signal passing along a signal pathway;
• changing a state of a compensating block from a first state to a second state to compensate for the DC offset that is expected;
• and
• changing the state of the compensating block back to the first state.

A radio frequency receiver operable to receive packets of radio signals divided by slots, the slots defining slot boundaries, comprising

• a component block;
• a compensating block;
• a signal pathway passing through the component and compensating blocks;
• memory for storing an estimated DC offset;
• and
• control circuitry operable for changing the component block from a first to a second state at a slot boundary, said change from first to second state expected to induce an actual DC offset that is substantially equal to the estimated DC offset;
• said control circuitry further being operable for changing the compensating block from a nominal to a compensating state.
