  • Abstract
    Subcarrier ordering is a ranking of the subchannels of a multicarrier communication system according to a quality criterion. We describe and evaluate two techniques for subcarrier ordering in half-duplex packet radio systems, including OFDM dynamic spectrum access systems. The ordering techniques require no estimates of subchannel gains or subcarrier signal strengths. The performance of each technique is evaluated for channels with fading and for channels with interference and fading.
