Patent attributes
A configurable Orthogonal Frequency Division Multiplexing (OFDM) device comprises a first transform stage configured to generate a first stage output having a first length, a second transform stage configured to operate in conjunction with the first transform stage and to generate a second stage output having a second length, and a switching network configured to selectively connect the second transform stage with the first transform stage to select the first stage output or the second stage output. A method of configuring an Orthogonal Frequency Division Multiplexing (OFDM) device comprises determining an appropriate OFDM mode, based on the OFDM mode determined, selectively connecting a first transform stage of the device with a second transform stage of the device, wherein the first transform stage has a first stage output and the second transform stage has a second stage output, and selecting the first stage output or the second stage output.
