1. A femtocell base station that is configured for limiting adjacent channel interference, comprising:

  • a transmitter that is configured to transmit downlink signals to a mobile station;

    a transmit pulse-shaping filter that limits bandwidth of the downlink signals transmitted by the femtocell base station;

    a narrower transmit pulse-shaping filter that limits the bandwidth of the downlink signals transmitted by the femtocell station to a greater extent than the transmit pulse-shaping filter;

    a processor;

    memory in electronic communication with the processor; and

    instructions stored in the memory, the instructions being executable by the processor to cause the femtocell base station to switch between the transmit pulse-shaping filter and the narrower transmit pulse-shaping filter.
