    • PURPOSE: A constellation mapping system and a mapping method thereof are provided to reduce a size of a memory by storing only constellation dots within one quadrant without storing all constellation dots to the memory. CONSTITUTION: A constellation mapping system includes a memory(620), an address generation block(610), a complement logic block(630), and a scaler block(640). The memory(620) is used for storing a constellation value corresponding to one of quadrants of each constellation. The address generation block(610) receives constellation dot data, bits-per-symbol information, and symbol validity information and generates address information including the constellation value and quadrant information for indicating the quadrant including the constellation dot data. The complement logic block(630) is used for inverting the constellation value of the memory. The scaler block(640) multiplies a predetermined gain by an output of the complement logic block on the basis of a baud rate and outputs the multiplied result or the output of the complement logic block. The constellation mapping system further includes a latch block(650) to output a re-timing value of an output of the scaler block.

    • PURPOSE: An inverse sinc filter is provided to be capable of compensating frequency distortion by digital/analog conversion at a specific frequency band. CONSTITUTION: An inverse sinc function approximation part(200) approximates an input signal into an inverse sinc function format corresponding to a control coefficient and generates an approximated inverse sinc function. An adder adds the approximated inverse sinc function with the input signal and compensates frequency distortion of a sinc type in the input signal.

CONSTITUTION: A frequency diffusion high-speed wireless transmitter/receiver includes a serial-to-parallel converter(211) for converting a serial transmission data to a parallel transmission data. A coder diffusion part(213) diffuses an output signal of the serial-to-parallel converter. A multiplexer(215) multiplexes an output signal of the coder diffusion part. A transmission processor(220) part receives the diffusion code and the output signal of the multiplexer, and transmits a transmission signal. A receiving processor part(230) receives a transmission signal of the transmission processor part. A multiplier(241) multiplies output signals of the receiving processor parts.
