Abstract :
We compare single user digital multi-carrier spread spectrum modulation with direct sequence spread spectrum in the presence of frequency-selective multipath fading. We derive closed-form expressions for the bit error probability and show that MC-SS is more robust to multipath fading than is DS-SS
