<p>A transmission system comprising a transmitter operable to transmit signals by using orthogonal frequency division multiplexing, and a plurality of reception devices operable to receive signals transmitted by the transmitter. The transmitter includes a power controller to control gain for first signals (Si), including corresponding guard intervals, to be transmitted to the plurality of reception devices in an area formed by the transmitter to be greater than gain for second signals (Sj), including corresponding guard intervals, to be transmitted to a specific device in the area, wherein said first signals and said second signals are time divisionally multiplexed.</p> |
