Patent ID: 7248646

Claim:
A reconfigurable communication transmitter core, comprising: a reconfigurable digital pulse-shaping filter to perform pulse-shaping operations upon a digital modulated signal; and a finite state machine to control operation of said digital pulse-shaping filter; said finite state machine reconfiguring said digital pulse-shaping filter based upon air-interface parameters; said digital pulse-shaping filter including, a first memory for storing coefficients, a second memory for storing data, a multiplier to multiply a data value stored in said second memory with a corresponding coefficient value stored in said first memory, a register, an adder to add each multiplication product from said multiplier with the content of said register, said register storing the sum from said adder, and a rounding unit, operatively connected to said register, to round-off a content of said register and to provide the rounded-off content as an output of the reconfigurable communication transmitter core; said finite state machine including, an index generation circuit to convert input data bits defining a certain signal pattern history to a first index value, the first index value being associated with said second memory and linked to an address location in said first memory, and an address generation circuit to generate a second index value associated with said first memory, said second index value enabling access to a memory location in said first memory, each memory location containing an output of an equivalent pulse shaped filtered waveform.
