On the Ergodic Sum-Capacity of Decentralized Multiple Access Channels
TL;DR: This work considers a fast fading AWGN multiple-access channel with full receiver CSI and distributed CSI at the transmitters to evaluate the ergodic sum-capacity of this decentralized model, under identical average powers and channel statistics across users.
Proceedings ArticleDOI
Decentralized power adaptation in ergodic fading multiple access channels
Kamal Singh,Sibi Raj B Pillai +1 more
TL;DR: A structural property is derived that any optimal decentralized power control scheme must follow, and this property is used to suggest a modified power control schemes and numerical results suggest that the scheme proposed outperforms the existing ones.
Proceedings ArticleDOI
On fading MAC channels with asymmetric CSI
TL;DR: A distributed MAC setting with block-wise flat fading links and full receiver CSI (channel state information) is considered, which proposes efficient power-allocation and rate-adaptation strategies which are sum-rate optimal when users in each subset observe identical fading distributions chosen from a class.
Proceedings ArticleDOI
A simulation study of performance of joint soft demapping-viterbi decoding in DVB-T system
TL;DR: Simulation results confirm the advantage of using soft-dec decision decoding over the hard-decision type, and evaluate and compare the performances of Viterbi decoding schemes based on soft decision and hard decisions, with results applicable to the Digital Video Broadcast-Terrrestial (DVB-T) standard.
Proceedings ArticleDOI
On Decentralized Power Control for Ergodic MIMO Multiple Access Channels
TL;DR: This work considers a MIMO-MAC model where each transmitter is only aware of its own fading realization, and proposes decentralized power control schemes that closely characterize the sum-capacity in several regimes of interest.
