ABSTRACT:
Methods and systems for calibrating transceivers are described. Analog transceiver components create errors, such as gain and offset errors in a receiver or a transmitter portion, which are compensated by adjusting digital signal processing in the computing portion of the transceiver. Errors can be measured in a calibration procedure and determined compensating values stored in a memory device of the transceiver. These values can then be retrieved when the transceiver is initialized for usage during signal processing of signals received by and transmitted by the transceiver.
