چکیده
© 2014 Yonghoon Choi 953 http://dx.doi.org/10.4218/etrij.14.0113.0843 This paper studies the uplink resource allocation for multiple radio access (MRA) in reconfigurable radio systems, where multiple-input and multiple-output (MIMO) multicarrier-code division multiple access (MCCDMA) and MIMO orthogonal frequency-division multiple access (OFDMA) networks coexist. By assuming multi-radio user equipment with network-guided operation, the optimal resource allocation for MRA is analyzed as a cross-layer optimization framework with and without fairness consideration to maximize the uplink sum-rate capacity. Numerical results reveal that parallel MRA, which uses MC-CDMA and OFDMA networks concurrently, outperforms the performance of each MCCDMA and OFDMA network by exploiting the multiuser selection diversity.

In this paper, two candidates for a next generation (4G) downlink system in a multi−cell environment are studied in respect to their error performance. We investigate on the one hand, an orthogonal frequency division multiplexing (OFDM) based multiple access scheme (OFDMA), and on the other hand, a multi−carrier code division multiple access (MC−CDMA) scheme. The studies of both transmission sc...

The MC-CDMA transmission technique is seen as a candidate for beyond 3G systems. It benefits from the high bandwidth efficiency of multi-carrier systems and the flexibility and granularity offered by CDMA for resources allocation. In the framework of the IST MATRICE European project, a MC-CDMA beyond 3G system has been defined and extensively studied. This paper describes the sensitivity of thi...
