Downlink channel estimation for LTE OFDMA system under radio environment
The 3rd generation partnership project (3GPP) long term evolution (LTE) project is designed for high speed data rate, higher spectral efficiency, improved services, and lower latency as well as high-capacity voice support. LTE uses orthogonal frequency division multiplexing access (OFDMA) scheme for the downlink and single carrier frequency division multiple access (SCFDMA) in uplink. Main chal...
متن کاملSum rate maximization for multi-cell downlink OFDMA with subcarrier pair-based opportunistic DF relaying
This paper considers multi-cell decode-and-forward (DF) relay-aided orthogonal frequency division multi-access (OFDMA) downlink systems, in which all sources and relays are coordinated by a central controller for resource allocation (RA). The improved subcarrier pair-based opportunistic DF relaying protocol proposed and studied in the IEEE International Conference on Communications, Beijing, 37...
متن کاملDistributed algorithms for sum rate maximization in multi-cell downlink OFDMA with opportunistic DF relaying
This paper considers a multi-cell orthogonal frequency division multiple access (OFDMA) downlink systemwith several decode-and-forward (DF) relay stations (RSs) aiding the base station (BS) transmissions. The problem considered is the maximization of the system sum rate with a total power constraint in each cell. An iterative semi-distributed resource allocation (RA) algorithm is first proposed...

متن کاملPrimal Decomposition-Based Method for Weighted Sum-Rate Maximization in Downlink OFDMA Systems
We consider the weighted sum-rate maximization problem in downlink Orthogonal Frequency Division Multiple Access (OFDMA) systems. Motivated by the increasing popularity of OFDMA in future wireless technologies, a low complexity suboptimal resource allocation algorithm is obtained for joint optimization of multiuser subcarrier assignment and power allocation. The algorithm is based on an approxi...
