Summary: 
This comment rectifies the auto-correlation function of the raised-cosine pulse shaping filter response derived in the above paper, giving its exact expression. We give, not only the exact solution for the auto-correlation taken at multiples of the chip period, Φ(rTc), but also for its entire domain, Φ(τ). Nevertheless, due to an approximation made in [1], the conclusions reached therein remain valid.
