Journal ArticleDOI
A least-squares approach to blind channel identification
TL;DR: A new blind identification algorithm based solely on the system outputs is proposed and necessary and sufficient identifiability conditions in terms of the multichannel systems and the deterministic input signal are presented.
Journal ArticleDOI
Computationally efficient bandwidth allocation and power control for OFDMA
D. Kivanc,Guoqing Li,Hui Liu +2 more
TL;DR: Numerical results demonstrate that the proposed low complexity algorithms offer comparable performance with an existing iterative algorithm.
Journal ArticleDOI
A high-efficiency carrier estimator for OFDM communications
TL;DR: Two blind carrier offset estimation algorithms are presented by exploiting the intrinsic structure information of OFDM signals to offer the accuracy of super resolution subspace methods, viz., MUSIC and ESPRIT, without involving computationally intensive subspace decompositions.
Journal ArticleDOI
OFDM blind carrier offset estimation: ESPRIT
TL;DR: The intrinsic structure information of OFDM signals is exploited to derive a carrier offset estimator that offers the accuracy of a super resolution subspace method, ESPRIT.
Journal ArticleDOI
Downlink Radio Resource Allocation for Multi-Cell OFDMA System
TL;DR: The results indicate that with reasonable signaling overhead, the RRC protocol and the associated algorithms yield excellent performance for both real-time and non real- time services, even under fast fading.
