Abstract
The forward link (base to mobile) user capacity of Reed Solomon (RS) coded FFH/CDMA channels is investigated. A new error-and-erasure correction scheme for the RS coded FFH/CDMA channels is proposed. It is shown that the proposed error-and-erasure correction scheme for the RS(255, 223) code with the optimal code rate 0.87 can increase the normalised user capacity by 17% over that without coding when the deletion probability is 0.01.
