Spectral Efficiency and Optimal Medium Access Control of Random Access Systems over Large Random Spreading CDMA
Yi Sun · IEEE Transactions on Communications · 2009
This paper analyzes the spectral efficiency as a function of medium access control (MAC) for large random spreading CDMA random access systems that employ a linear receiver. It is shown that located at higher than the physical layer, MAC along with spreading and power allocation can effectively perform spectral efficiency maximization and near-far mitigation.
