DIGITAL WIRELESS DEVICE AND TRANSMISSION DATA SIGNAL PROCESSING METHOD

PROBLEM TO BE SOLVED: To reduce packet collisions due to transmission delay when a preamble length is based on STD specifications (is not shortened). SOLUTION: The digital wireless device is provided with: a MAC part for outputting transmission data and transmission enable signals; a preamble generation part for generating original preamble data other than preamble data inside the transmission data; a digital signal processing means for executing digital signal processing to the transmission data and the original preamble data; and a preamble data storage means for holding the preamble data generated by the preamble generation part, to which the digital signal processing is executed. When detecting that the transmission enable signals are turned on, the preamble data storage means immediately outputs the preamble data (residual part data) to which the digital signal processing is executed. After the output of the preamble data (residual part data) is completed, the digital signal processing means outputs the transmission data including incomplete preamble data to which the digital signal processing is executed.
