RADIO TRANSMISSION APPARATUS AND RADIO TRANSMISSION METHOD

摘要

When performing transmission using the OFDM-CDMA method, sub-carriers in which spread signals are arranged only in the frequency axis direction #1 to #m, #2m+1 to #3m, #3m+1 to #4m, #4m+1 to #5m and sub-carriers in which spread signals are arranged in the frequency axis direction and temporal axis direction #m+1 to #2m are created and they are transmitted simultaneously.
