An energy allocation scheme is developed for multi-code code division multiple access (CDMA) systems to allocate the total energy to two-groups of code channels whilst considering successive interference cancellation to minimize the allocated energy. With a simplified energy calculation formulation, the required computational complexity to improve the transmission data rates is relatively reduced. This proposed scheme is also combined with a packet-based channel coding scheme, which provides regenerated symbols to be removed during the interference cancellation process.
