Patent ID: 7529315

Claim:
A multicarrier transmitting apparatus comprising: a dividing section that divides transmit data into high-quality transmit data requiring good quality and ordinary transmit data other than said high-quality transmit data; a subcarrier allocation section that rearranges said high-quality transmit data and said ordinary transmit data such that said high-quality transmit data is allocated to subcarriers in a vicinity of a center frequency in a predetermined frequency domain and said ordinary transmit data is allocated to subcarriers in a vicinity of both ends in the predetermined frequency domain, and that varies in accordance with channel quality a range of subcarriers to which said high-quality transmit data is allocated and a range of subcarriers to which said ordinary transmit data is allocated; and an orthogonal frequency division multiplexing section that performs orthogonal frequency division multiplexing of said high-quality transmit data and said ordinary transmit data rearranged by said subcarrier allocating section.
