SWITCHING BETWEEN DIFFERENT TRANSMIT/ RECEIVE PULSE SHAPING FILTERS FOR LIMITING ADJACENT CHANNEL INTERFERENCE |
摘要 |
<p>A femtocell base station includes a transmitter that transmits downlink signals to a mobile station, a receiver that receives uplink signals from the mobile station, a standard transmit pulse-shaping filter, and a narrower transmit pulse-shaping filter that limits the bandwidth of the downlink signals to a greater extent than the standard transmit pulse-shaping filter. The femtocell base station also includes a standard receive pulse-shaping filter and a narrower receive pulse-shaping filter. The femtocell base station is configured to switch between the standard transmit pulse-shaping filter and the narrower transmit pulse-shaping filter, and to switch between the standard receive pulse-shaping filter and the narrower receive pulse-shaping filter. A mobile station may switch from a standard transmit pulse-shaping filter to a narrower transmit pulse-shaping filter to limit uplink interference. A mobile station may switch from a narrower transmit pulse-shaping filter to a standard transmit pulse-shaping filter to achieve a higher data rate.</p> |
