Patent ID: 8526999

Claim:
A signal converter, connected with a plurality of radio units, for converting a not-weighted signal to a weighted signal, the signal converter comprising: a first interface unit operable to receive input of a single time domain signal that contains a Cyclic Prefix (CP) and is to be used for a wireless transmission; a first converting unit operable to remove the CP from the time domain signal received by the first interface unit, and convert the time domain signal, from which the CP has been removed, to a frequency domain signal which is a signal constituted from frequency components; a generating unit operable to generate a plurality of different frequency domain signals by performing a weighting calculation onto the frequency domain signal; a second converting unit operable to transform the plurality of frequency domain signals generated by the generating unit to a plurality of time domain signals, attach a CP to each of the time domain signals, and output the time domain signals; and a second interface unit operable to output the plurality of time domain signals output from the second converting unit, one-to-one to different radio units.
