Method to calibrate RF paths of an FHOP adaptive base station
First Claim
1. A method comprising:
- periodically interrupting a frequency hopping process while a call is in progress, wherein said periodically interrupting comprises routing said call to an RF beacon transceiver apparatus, and wherein said frequency hopping process is of a frequency hopping adaptive base transceiver station having an adaptive antenna array including RF traffic transceiver apparatus chains;
calibrating an antenna transmit path for one of said RF traffic transceiver apparatus chains at a frequency selected from a plurality of predetermined frequencies defined by a hop list to determine a set of weighting parameters for said antenna transmit path at said frequency; and
returning said call to said frequency hopping process,wherein said calibrating comprises calculating adjustment values to achieve a best or a desirable null for said one of said RF traffic transceiver apparatus chains.

Abstract
A method for calibration of RF paths of a frequency hopping adaptive base transceiver station is provided. The method of calibration calibrates a wireless cellular telecommunication system with a frequency hopping adaptive base transceiver station including an adaptive antenna array with two or more RF traffic transceiver apparatus chains. The wireless cellular telecommunication system communicates with mobile units on a frequencies defined by a hop list. The method of calibration includes the step of periodically interrupting a frequency hopping process of the frequency hopping adaptive base transceiver station while calls are in progress. The method of calibration further includes the step of calibrating an antenna transmit path for a RF traffic transceiver apparatus chain at a frequency selected to include one or more frequencies in the hop list to determine a set of weighting parameters for the antenna transmit path at the one or more frequencies. A self-calibrating frequency hopping adaptive base transceiver station is also provided.
