Abstract: A receiver receives a desired radio sub-channel transmitted with an unwanted radio sub-channel by producing signal branches from a received radio signal by treating orthogonal components of the received signal separately and also by using one or both of oversampling and multiple receive antennas. Channel estimates for both the desired and unwanted radio sub-channels are produced for signal branches. The unwanted radio sub-channel bits are estimated from a non-stacked form of the received radio signal. The channel estimates and the estimate of the unwanted radio sub-channel bits are used to reconstruct unwanted radio sub-channel components separately for signal branches. Desired radio sub-channel signal branches are produced by subtracting a corresponding one of the reconstructed unwanted radio sub-channel components from signal branches. A non-stacked desired signal is produced by combining the desired radio sub-channel signal branches. The non-stacked desired signal is processed to receive the desired radio sub-channel.

Abstract: Methods and systems for performing interference mitigation (immunity management) in a radio communication device. A list of frequencies is provided from at least one radio subsystem to an immunity management (IMM) module. The IMM module determines whether any of the frequencies in the list represent a conflict with harmonics associated with one or more clock frequencies associated with one or more embedded systems. If a conflict exists, then the IMM module makes a change in the fundamental frequency of the corresponding clock to remove the conflict, while also ensuring that other frequencies in the list are not impacted by the change. The potential need to change clock frequencies can be evaluated at state transitions of the device, e.g., call establishment, call release, handover or channel re-allocation events.
