When transmission is performed using the OFDM-CDMA method, subcarriers #1 through #m, #2m+1 through #3m, #3m+1 through #4m, and #4m+1 through #5m in which spread signals are allocated only in the frequency axis direction, and subcarriers #m+1 through #2m in which spread signals are allocated in both the frequency axis direction and the time axis direction, are formed, and these are transmitted simultaneously. |
