Abstract:
1. A method comprising: in an electronic receiver comprising nonlinear distortion modeling circuitry, interference estimation circuitry, and sequence estimation circuitry: receiving an orthogonal frequency division multiplexing (OFDM) symbol in the form of an electromagnetic signal; generating, in said nonlinear distortion modeling circuitry, a nonlinear distortion model that models nonlinear distortion introduced to said received electromagnetic signal en route to said sequence estimation circuitry; estimating, in said interference estimation circuitry, inter-subcarrier interference present in said received OFDM symbol based on said generated nonlinear distortion model; and sequentially processing, in said sequence estimation circuitry, a plurality of received virtual subcarrier values of said OFDM symbol using said estimated inter-subcarrier interference, said processing resulting in decisions as to a plurality of transmitted virtual subcarrier values that correspond to said plurality of received virtual subcarrier values.
