Chip rate selectable square root raised cosine filter for mobile telecommunications

摘要

A square root raised cosine filter for a mobile transceiver may be adapted to operate with a variety of potential chip rates such as the four chip rates associated with IMT-2000 standard. The signal produced by the filter may be adjusted based on a variety of potential chip rates. One of the adjusted filter signals may be selected as the resulting filter output, depending on the particular chip rate selected for the mobile transceiver.
