Belief-propagation-based joint channel estimation and decoding for spectrally efficient communication over unknown sparse channels
Philip Schniter
We consider spectrally-efficient communication over a Rayleigh N-block-fading channel with a K- sparse L-length discrete-time impulse response (for 0<K<L<N), where neither the tran…
Joint Scheduling and Resource Allocation in the OFDMA Downlink: Utility Maximization under Imperfect Channel-State Information
Rohit Aggarwal, Mohamad Assaad, C. Emre Koksal +1
We consider the problem of simultaneous user-scheduling, power-allocation, and rate-selection in an OFDMA downlink, with the goal of maximizing expected sum-utility under a sum-pow…
On Communication over Unknown Sparse Frequency-Selective Block-Fading Channels
Arun Pachai Kannu, Philip Schniter
This paper considers the problem of reliable communication over discrete-time channels whose impulse responses have length and exactly non-zero coefficients, and whos…
Multiuser Scheduling in a Markov-modeled Downlink using Randomly Delayed ARQ Feedback
Sugumar Murugesan, Philip Schniter, Ness B. Shroff
We focus on the downlink of a cellular system, which corresponds to the bulk of the data transfer in such wireless systems. We address the problem of opportunistic multiuser schedu…
