1. A transmitting apparatus configured for transmitting orthogonal frequency division multiplexing (OFDM) signals for communication in a wireless communication system, the transmitting apparatus comprising:

  • signal generation and transmission components configured to;

    generate and transmit OFDM signals by using a part or all of a frequency band comprising more than three frequency channels, wherein each of the more than three frequency channels comprises a plurality of subcarriers,generate and transmit an OFDM signal to a receiving apparatus that is a limited band apparatus capable of receiving only part of the frequency band and having a reception bandwidth of a number of frequency channels, wherein the OFDM signal is transmitted to the receiving apparatus by using less than or equal to the number of frequency channels, andallocate (i) the OFDM signal to one or more frequency channels and (ii) no power to a first number of subcarriers at a first edge of the one or more frequency channels and a second number of subcarriers at a second edge of the one or more frequency channels,wherein the first number of subcarriers and the second number of subcarriers are determined as a function of reception capabilities of the receiving apparatus having the reception bandwidth.
