Performance of Generalized Multicarrier DS-CDMA Using Various Chip Waveforms
Yang, L-L. and Hanzo, L. (2003) Performance of Generalized Multicarrier DS-CDMA Using Various Chip Waveforms. IEEE Transacations on Communications, 51, (5), 748-752.
In this letter, we extend our investigation of generalized multicarrier direct-sequence code-division multiple access by considering two additional types of chip waveforms, namely, the time-domain half-sine and raised-cosine chip waveforms, in addition to the rectangular chip waveform. A range of closed-form equations are provided for quantifying the effect of both the multipath interference and the multiuser interference, when using partially overlapping subcarriers. These closed-form formulas allow us to evaluate the bit-error rate performance of arbitrary code-division multiple access schemes using overlapping subbands with the aid of the standard Gaussian approximation. Index Terms—Code-division multiple access (CDMA), multicarrier, frequency-selective fading.
