Abstract
An IC modulation processor ( ) may be configured to operate in a single chip mode to accommodate baud rates up to a maximum clock rate for the processor ( ) and in a dual chip mode to accommodate baud rates in excess of the maximum clock rate. The IC modulation processor ( ) performs digital processing on a communication signal which conveys an input data stream ( ). A pulse shaping filter ( ) is provided following a phase mapper ( ). The pulse shaping filter ( ) is implemented as a pair of half-filters. Pulse shaping is distributed between two IC modulation processors ( ) in the dual chip mode. An interpolator ( ) and linearizer ( ) follow the pulse shaping filters ( ).
