A Novel Degradation Scheme Based on User Satisfaction in CDMA Systems

Article Preview

Abstract:

Within the past few years, a great deal of attention has been drawn towards the CDMA system. The state of a CDMA system has two cases: saturation and instauration. After the system is saturated, no more users are allowed to access to CDMA systems with traditional method. In order to enhance the maximum number of users and the all users’ satisfaction while guaranteeing users’ quality of service (QoS) –SINR (signal-to-interference–plus-noise) requirement, this paper presents a degradation scheme based on user satisfaction in CDMA systems. Simulation results show that the proposed scheme can be allowed more users to access to and increase the total users’ satisfaction, leading to higher system capacity and resource utilization.
