Abstract

Disclosed are wireless communication systems and methods for calibrating same. The communication systems may include first wireless transceivers having: (a) a modem, and (b) one or more Radio Frequency (RF) chain pairs. There may also be included a sounding circuit block. A calibrated switchable bridging block (CSBB) may switchably couple signals between the first transceivers and the sounding circuit block. Calibration control logic may regulate signal flow through said CSBB during a sounding sequence of said first wireless transceiver and may apply compensation coefficients to RF compensation circuits functionally associated with said the wireless transceiver RF chain pairs.
