Claim:
An interference-suppressing orthogonal frequency division modulation system comprising: a base station comprising: an interference-suppressing orthogonal frequency division modulation transceiver configured to communicate with an in-home terminal and including an interference-suppressing orthogonal frequency division modulation receiver and an interference-suppressing orthogonal frequency division modulation transmitter; wherein the interference-suppressing orthogonal frequency division modulation receiver is configured to receive a data signal comprising a plurality of data points; and wherein the interference-suppressing orthogonal frequency division modulation transmitter is configured to broadcast the data signal that is received to the in-home terminal, the data signal that is received being divided into a first plurality of L frequency groups, each of the L frequency groups being further divided into a second plurality of M orthogonal frequency bins to reduce ultra-wide bandwidth emissions, where L and M are integers, and each of the M orthogonal frequency bins receiving a data stream containing the plurality of data points in the data signal, wherein any one of the plurality of data points in the data signal that is received designated for a particular frequency group is recoverable from any one of the plurality of M orthogonal frequency bins within the particular frequency group, wherein each group of the L frequency groups comprises a plurality of adjacent frequency bins and each group of the L frequency groups is assigned to a single user, wherein a group width of L groups is selected where the group width is narrower than a coherence bandwidth of a channel and the group width is wide enough to suppress a narrow-band interference.
