Abstract

For wideband code-division multiple-access systems, this letter introduces a multicarrier modulation scheme that performs the spreading in the time and frequency domains simultaneously. This scheme attains higher flexibility and spectrum efficiency because system parameters can be selected at will. The performance is compared with that of a single carrier RAKE system by calculating the probability of error over a frequency-selective Rayleigh fading channel. The proposed scheme outperforms the single carrier RAKE system if the system parameters are selected properly for given conditions such as bandwidth and delay spread.
