Survey on Optimization Techniques used for Resource Allocation in Wireless Communication System (original) (raw)

In recent years telecommunication is playing a major role in the field of communication. In wireless communication systems, the necessity to provide more number of users with high-rate communication links leads to optimization problems. Demands of resource block assignment, interference and power consumption at base station and mobile devices have to be answered in the face of time-varying frequency-selective channels. In addition, the heterogeneity of recent mobile services means that delay and data rate requirements vary significantly between applications and users. These requirements are summarized as resource allocation problems.
