An Efficient Utility & Sum Rate Optimization in MC-CDMA Communication System

Dency C Koshy

Abstract: This paper is mainly concerned with the problem of utility and sum rate optimization in an OFDM network. So first we design the uplink and downlink multicarrier wireless network. The utility is related to the level of satisfaction of the MUs with respect to the communication link, and it could be associated to the efficiency in the data transmission with respect to the required power. Capacity is related to the maximum achievable data rates in the network. The data estimation at the mobile unit (MUs) is carried out by a simple matched filter

Keywords: MC-CDMA, utility, capacity, quality of services, sum-rate maximization
