Patent No
3419236
Abstract
A transmitter configured to transmit a transmit signal, wherein the transmit signal comprises a plurality of subcarriers, wherein the transmitter is configured to filter a subcarrier of the plurality of subcarriers with a pulse shaping filter, wherein the transmitter is configured to transmit, on a first pilot subcarrier of the plurality of subcarriers of the transmit signal, a training sequence for an intercarrier interference cancellation at a receiver, wherein the transmitter is configured to transmit, on a second pilot subcarrier of the plurality of subcarriers of the transmit signal, payload data using a first modulation order for an intercarrier interference cancellation at the receiver, wherein the transmitter is configured to transmit, on one or more of the remaining subcarriers of the plurality of subcarriers, payload data using a second modulation order, and wherein the first modulation order is lower than the second modulation order.
