Abstract: One embodiment is directed to a distributed antenna system comprising a host unit and at least one remote antenna unit that is communicatively coupled to the host unit. The host unit is configured to communicate a downstream transport signal from the host unit to the remote antenna unit. The remote antenna unit to which the downstream transport signal is communicated uses the downstream transport signal to generate a downstream radio frequency signal for radiation from an antenna associated with the remote antenna unit. The remote antenna unit is configured to communicate an upstream transport signal from the remote antenna unit to the host unit, wherein the upstream transport signal is generated from a received upstream radio frequency signal received at the remote antenna unit. The remote antenna unit is configured to perform self-interference suppression processing in an upstream signal path using, as an input thereto, a feedback signal derived from the downstream radio frequency signal radiated from the antenna. Other embodiments are disclosed.

Abstract: Communication system includes first unit; and second unit(s) having processing unit(s), downstream signal path(s), and upstream signal path(s). First unit communicates downstream digital transport signal (including digital representation of original downstream RF signal received at first unit) to second unit(s). Second unit uses processing unit and downstream signal path to generate downstream RF signal (for radiation from antenna) from downstream digital transport signal; and communicates upstream digital transport signal (generated from upstream RF signal received at second unit(s) using processing unit(s) and upstream signal path(s)) to first unit. Upstream digital transport signal includes digital representation of received upstream RF signal. Feedback path digitizes downstream RF signal(s) to provide digital representation(s) of downstream RF signal radiated from antenna to processing unit(s). Second unit pre-distorts input signal to downstream signal path for non-linearities in downstream signal path using digital representation of downstream RF signal radiated from antenna as received from feedback path.

Abstract: A mobile device estimates a data symbol from a received signal by using one or more interference cancellation algorithms. For one interference cancellation algorithm, the mobile device calculates (302) a Channel State Information (CSI) of an interfering sector and calculates (304) a CSI of a serving sector at a different time. The mobile device then determines (310) a correction factor to the CSI of the interfering sector by, for example, estimating a Doppler speed and a time difference between a first time interval like a preamble symbol and a second time interval like any symbol of interest in the data zone. Using the correction factor, the mobile device updates outdated interference information. The mobile device can cancel interference in the received signal distorted by co-channel interference by using the updated interference information. Also, the mobile device can be configured to combine results of multiple interference cancellation algorithms based on the applicability of the individual interference cancellation algorithms in particular scenarios.
