Performance Evaluation of Multihop Cellular Systems and Rate Adaptive Cellular Systems

We attempt to analytically formulate the spectral efficiency and outage probability of multihop cellular systems, in which mobile stations and base stations can communicate by using multihop relaying. This multihop relaying has the same ability as symbol rate control to enhance the end-to-end communication range at the loss of spectral efficiency. According to this commonality, a similar methodology to formulate the performance of rate-adaptive cellular systems is used. Numerical results reveal that multihop relaying is superior to symbol rate control in terms of both coverage and spectral efficiency
