Calibration for a receiver by using neighboring receive paths

An apparatus for wireless communications, comprising:

• a first receiver having a first oscillating signal generation circuit selectively coupled to a local-oscillator (LO) input of each of one or more mixers of the first receiver and a second oscillating signal generation circuit selectively coupled to the LO input of each of the one or more mixers of the first receiver;
• a second receiver having a third oscillating signal generation circuit coupled to an LO input of each of one or more mixers of the second receiver;
• and
• a signal path selectively coupling an output of the first oscillating signal generation circuit to an input of the second receiver.

A method for receiver calibration, comprising:

• generating a first oscillating signal via a first oscillating signal generation circuit of a first receiver;
• splitting the first oscillating signal to generate a first plurality of oscillating signals;
• providing the first plurality of oscillating signals to respective signal inputs of a first plurality of mixers of a second receiver;
• generating, via a second oscillating signal generation circuit of the second receiver, a local-oscillator (LO) signal;
• providing the LO signals to respective LO inputs of the first plurality of mixers of the second receiver;
• and
• down-converting the first plurality of oscillating signals via the first plurality of mixers to yield down-converted signals;
• processing the down-converted signals for calibration;
• and
• configuring one or more components of the second receiver based on the processing.
