Abstract
A radio system having multi-standard mixed mode radios is described. The mixed mode radios are used to support combining of digital baseband from a first and a second radio equipment controller. A primary clock associated with the first radio equipment controller and a secondary clock associated with the second radio equipment controller is provided. The quality of the primary clock is evaluated and the primary clock is referenced to the first radio equipment controller if the clock is determined to have appropriate quality factors. The quality of the secondary clock is then evaluated and the secondary clock is referenced to the second radio equipment controller if the secondary clock is determined to have appropriate quality factors. The second radio equipment controller is then referenced to the primary clock once the primary and secondary clocks are aligned.
