Abstract
Systems and techniques for signal filtering are described. A bandpass filter is defined so as to provide for a reduced rolloff region so as to avoid interference with an adjacent carrier. Definition of the bandpass filter provides for a frequency response that compensates for loss of signal components in the rolloff region. Definition of the bandpass filter may be based at least in part on characteristics of a specified legacy filter used by devices from which signals may be received or to which signals may be transmitted.
