ULTRA-WIDE BANDWIDTH SYSTEM AND METHOD FOR IN-PREMISES WIRELESS NETWORKING

摘要

An IS-OFDM system for ultra-wideband (UWB) wireless communications that suppresses narrow-band interference, comprising an in-premises base station (IBS) is described. The IBS further comprises an IS-OFDM transceiver for communicating with a plurality of in-premises terminals (ITs) without creating interference outside an in-premises perimeter. Further, a method for operating an IS-OFDM system for ultra-wideband (UWB) wireless communications that suppresses narrow-band interference and provides local area networking services, in-premises distribution of broadcast cable channels and in-premises wireless access and routing to external networks is described, without creating interference outside an in-premises perimeter.

1. A base station comprising:
an interference-suppressing orthogonal frequency division modulation transceiver for communicating 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 for receiving a data signal comprising a plurality of data points; and wherein the interference-suppressing orthogonal frequency division modulation transmitter is for broadcasting the data signal that is received to the in-home terminal, the data signal that is received being divided into a plurality of L frequency groups, each of the plurality of L frequency groups being further divided into a plurality of M orthogonal frequency bins, where L and M are integers, and each of the plurality of 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 plurality of L frequency groups comprises a plurality of adjacent frequency bins and each group of the plurality of L frequency groups is assigned to a single user, wherein a group width of the plurality of L frequency groups is selected where the group width is wider than an interference bandwidth.
