Patent ID: 8514695

Claim:
A method for wideband wireless transmission, comprising: serial-to-parallel converting inputted serial data symbols to obtain parallel data symbols; coding each of the obtained parallel data symbols; superimposing the coded data symbols; and subjecting data symbols obtained from the superimposing to Inverse Fast Fourier Transform and transmitting the transformed data symbols; and wherein the method further comprises, before the Inverse Fast Fourier Transform: mapping the data symbols obtained from the superimposing to subcarriers; and after the Inverse Fast Fourier Transform, adding Cyclic Prefixs to and windowing the transformed data symbols; and wherein the method further comprises, after the superimposing of the data symbols and before the mapping of the data symbols to subcarriers: serial-to-parallel converting the outputted data symbols to obtain parallel data symbols; and subjecting the parallel data symbols to Discrete Fourier Transform.
