TIME DEPENDENT EQUALIZATION OF FREQUENCY DOMAIN SPREAD ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING USING DECISION FEEDBACK EQUALIZATION

摘要

encode the subcarriers in the frequency domain using orthogonal spreading codes by which an orthogonal frequency division multiplexing signal a system and method for equalizing at least the steps of receiving a signal from the receiver 300, which demodulates the signal to generate a demodulated phase information, to generate the spread frequency domain representation of the demodulated phase information, and based on the adjustment value determining an equalizing represented by adjusting the power and phase of a frequency in a spread frequency domain representation, including the received subcarrier de-spread frequency domain by using the orthogonal code to generate the spread frequency domain representation equalized the de-spread to step, determining a value for each subcarrier of the received sub-carrier phase, the model comprising: spreading the spread value to the orthogonal sub-carrier determined by using an orthogonal code to generate a frequency representation, the model expression and the spread frequency equalizing The spread frequency calculating the expected error value and based on a domain representation, and to expected error values based on a step of calculating a new adjustment value. ;
