摘要： A method that incorporates teachings of the subject disclosure may include, for example, analyzing a signal to identify a present interference and extracting the interference from the signal. The extracting can include comparing a presence time for the interference with a reference time; if the presence time exceeds the reference time and at least one of a plurality of filters is available for filtering the present interference, an available filter of the plurality of filters is activated, thereby causing filtering of the interference from the signal. If no filter is available due to activation of the filters for filtering a plurality of previously identified interferences, a priority order is determined for the present interference and the previously identified interferences, based on their interference signal levels. The filters are assigned to the interferences in accordance with the priority order. Other embodiments are disclosed.

摘要： The disclosed embodiments relate to a system that performs channel-sounding operations in a multi-antenna wireless communication system. During operation, the system first performs channel-sounding operations between a first client and a second client in a first frequency band. These channel-sounding operations involve transmitting a series of known tones between the first client and the second client and using signals received as a result of the transmissions to finds a strongest path between the first client and the second client. Next, the system uses the identified strongest path to improve channel-sounding operations in a second frequency band.

摘要： The present disclosure relates to de-multiplexing at least one RF input signal feeding RF power amplifier circuitry to create multiple de-multiplexed RF output signals, which may be used to provide RF transmit signals in an RF communications system. Output transformer circuitry is coupled to outputs from the RF power amplifier circuitry to provide the de-multiplexed RF output signals, which may support multiple modes, multiple frequency bands, or both. The de-multiplexed RF output signals may be used in place of RF switching elements in certain embodiments. As a result, RF front-end switching circuitry in the RF communications system may be simplified, thereby reducing insertion losses, reducing costs, reducing size, or any combination thereof. Additionally, the output transformer circuitry may provide load line transformation, output transistor biasing, or both to the RF power amplifier circuitry.
