ESTABLISHING DECODING ORDER FOR SUCCESSIVE INTERFERENCE CANCELLATION

摘要

The present invention relates to a method for decoding a composite radio signal at a receiver said composite radio signal being a superposition of at least two signals by at least one transmitter, each signal being transmitted using the same radio resource on a set of frequency subchannels of an OFDM system. A robustness parameter is calculated for each signal. The estimated bit error rate for each signal is calculated using the signal power or signal-to-noise ratio, the modulation scheme and the coding scheme. The signal with the lowest estimated BER is decoded first.
