Abstract :
“Interleaved frequency-division multiple-access” (IFDMA) has previously been introduced as a new spread-spectrum multiple-access scheme for mobile communications. In this paper, performance results for uncoded and coded mobile radio transmission taking into account different equalization techniques are presented. As a result, equalization reduces the effects of intersymbol interference significantly. Uncoded IFDMA applying optimum equalization performs even better than uncoded multicarrier code-division multiple-access applying maximum likelihood multi-user detection. Moreover, in the case of coded IFDMA transmission coding gains up to 6.8 dB at a bit-error-rate of 10 -4 are achieved using a standard convolutional code
