Abstract
An apparatus and method for mitigation of receive power imbalance including estimating input power levels on two diversity receive branches in a receiver; computing a power imbalance between the two diversity receive branches and determining a weaker receive branch; setting a weakRX parameter based on the weaker receive branch; computing an intercept parameter cfor a switching curve based on the weakRX parameter; computing a threshold T based on the intercept parameter; and determining a switching decision for the receiver based on the threshold T.
