RADIO TRANSMISSION APPARATUS AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To improve SN ratio in a transmission signal, and to reduce the number of required bits of a transmission digital signal.

SOLUTION: A diffusion section 101 diffuses and processes transmission data. A delay section 108 absorbs delay time generated at a section power calculation section 102. A gain section 109 multiplies gain (Gn) outputted from a delay control section 107 by transmission digital data. A transmission RRC filter 110 restricts the bandwidth of the transmission digital data. A DAC 111 converts the transmission digital data to transmission analog data. An orthogonal modulator 112 allows the transmission analog data to be subjected to orthogonal modulation. An inverse gain section 113 multiplies gain (1/Gn) outputted from the delay control section 107 by the transmission analog data. A radio transmission section 114 performs specific radio processing to the transmission analog data for transmitting from an antennal 115.
