Method and system for providing digital compensation and vector calibration for a base station in a wireless network
First Claim
1. A method of providing digital compensation and vector calibration for a base station coupled to an antenna array, the method comprising:
- generating a transmit compensation/calibration (C/C) weight;
generating a receive C/C weight; and
performing a single process that simultaneously provides both digital compensation and vector calibration by directly applying the transmit C/C weight when generating outgoing radio frequency (RF) signals through the antenna array and the receive C/C weight when receiving incoming RF signals through the antenna array;
wherein the transmit C/C weight is generated by processing received outgoing RF signals that were received through at least one second antenna, the at least one second antenna being separate from the antenna array, the processing of the received outgoing RF signals configured to be performed by a compensation processor that is integrated into the base station; and
wherein the receive C/C weight is generated by processing received incoming RF signals that were transmitted through the at least one second antenna.

Abstract
A method for providing digital compensation and vector calibration for a base station in a wireless network is provided. The method includes performing a single process that is operable to provide simultaneously both digital compensation and vector calibration for the base station. According to one embodiment of the present disclosure, the single process is performed by receiving a transmitted signal based on a compensation/calibration (C/C) signal, processing the received signal, generating a C/C weight based on the processed signal, and using the C/C weight in a normal operational mode for the base station.
