Patent ID: 8218426

Claim:
A wireless communication method comprising steps of: transforming a block of received signal data in a plurality of stages arranged in series so that the block of received signal data is inputted into a first stage of the plurality of stages, processed successively through each stage of the plurality of stages, and a fast Fourier transformed block of signal data is outputted from a last stage of the plurality of stages, each stage of the plurality of stages comprising a butterfly and a data normalization device wherein the data normalization device of said each stage scales to a predetermined range output of the butterfly of said each stage by a normalization factor corresponding to the data normalization device of said each stage; for said each stage, adjusting the normalization factor corresponding to the data normalization device of said each stage, wherein the step of adjusting comprises determining, for said each stage, the normalization factor corresponding to the data normalization device of said each stage, wherein the step of adjusting is performed for each block of received signal data, said each block being of predetermined size; processing the fast Fourier transformed block to obtained a processed block of data; and using the processed block in an application of a wireless device, wherein the step of using the processed block comprises rendering information contained in the processed block.
