摘要： A method and apparatus to address multipath interference in a communication system is provided. The method comprises measuring an error signal in a signal path of the repeater, wherein the error signal contains desired communication signals, noise signals, and multipath coupling interference signals, computing a power spectrum of the measured error signal, and estimating a response of the multipath coupling interference by processing the power spectrum of the measured error signal using autoregressive estimation in the frequency domain. The method further comprises computing a plurality of FIR filter coefficients from the estimated response and applying the plurality of filter coefficients to an adjustable filter that generates a cancellation signal used to at least partially mitigate the multipath coupling interference signals.

摘要： Certain aspects and aspects of the present invention are directed to a distributed antenna system having a downlink communication path, an uplink communication path, and a non-duplexer isolator sub-system. The downlink communication path can communicatively couple a transmit antenna to a base station. The uplink communication path can communicatively couple a receive antenna to the base station. In one aspect, the non-duplexer isolator sub-system can be electronically configured for isolating uplink signals traversing the uplink communication path from downlink signals. In another aspect, a non-duplexer isolator sub-system can be configurable in one or more mechanical steps selecting a frequency response. In another aspect, a non-duplexer isolator sub-system can include an active mitigation sub-system.
