Abstract
An adaptive multi-receiver shared antenna matching system and corresponding method includes an antenna (101). A plurality receiver devices (103) are operably coupled to the antenna (101). Degree of coupling between each of the receiver devices (103) and the antenna (101) is dynamically alterable dependent on a degree of coupling model (200) and different signals received by the antenna (101).
