Spectral Efficiency Enhanced Cooperative Device-to-Device Systems With NOMA

Yancheng Ji;Wei Duan;Miaowen Wen;Payam Padidar;Jing Li;Nan Cheng;Pin-Han Ho

IEEE Transactions on Intelligent Transportation Systems
Year: 2021 | Volume: 22, Issue: 7 | Journal Article |
Cited by: Papers (26)
This paper considers a cooperative device-to-device (D2D) system with non-orthogonal multiple access (NOMA). We assume that the base station (BS) can simultaneously communicate with all users to satisfy the full information transmission requirement. In order to characterize the impact of the weak channel and different decoding schemes, two novel decoding strategies are introduced: single signal de...Show More

End-to-End Distortion Analysis of Nonorthogonal Layered Coding Over Relay-Assisted Networks

Payam Padidar;Pin-Han Ho;Limei Peng

IEEE Systems Journal
Year: 2020 | Volume: 14, Issue: 3 | Journal Article |
Cited by: Papers (3)
This article investigates cross-layer design of nonorthogonal layered (NOL) coding schemes over relay-assisted downlink of cellular networks that incorporates with successive refinement (SR) source code for transmission of adaptive multiresolution multimedia content. Two novel-layered relaying strategies, namely NOL compress-forward (NOL-CF) and NOL decode-forward (NOL-DF) coding, concatenated to ...Show More

A Deep Study on Layered Multi-Relay Non-Orthogonal Amplify-Forward Networks

Payam Padidar;Pin-Han Ho;Yancheng Ji;Wei Duan

IEEE Transactions on Wireless Communications
Year: 2020 | Volume: 19, Issue: 1 | Journal Article |
The paper introduces a cross-layer design for transmission of Successive Refinement (SR) source code inter-played with non-orthogonal layered code, deployed over a half-duplex multi-relay Non-orthogonal Amplify-Forward (NAF) network. Assuming the Channel State Information (CSI) is not available at the source node, firstly the achievable layered Diversity-Multiplexing Tradeoff (DMT) curve is derive...Show More

End-to-end distortion analysis of multicasting over orthogonal receive component decode-forward cooperative broadcast channels

Payam Padidar;Pin-Han Ho;James Ho

2016 IEEE Wireless Communications and Networking Conference
Year: 2016 | Conference Paper |
Cited by: Papers (2)
This paper studies the end to end distortion of transmission of a layered encoded source over a cooperative relay broadcast channel. A jointly optimised source-channel code is proposed to multicast a two-layered encoded source to two destinations. A degraded discrete memoryless broadcast channel is assumed, where the first destination with better channel conditions decodes both layers consisting o...Show More

Energy optimal multi-resolution multicast with asynchronous relaying

Zhi Chen;Pin-Han Ho;James She;Payam Padidar

2016 IEEE Wireless Communications and Networking Conference
Year: 2016 | Conference Paper |
The paper investigates the scenario of wireless multicast with a single transmitter and multiple relays that jointly deliver successively refined (or multi-resolution) sources to multiple receivers. An asynchronous cooperative joint source-channel coding (JSCC) protocol is proposed, which can mitigate the complexity and difficulty in signal synchronization under the wireless multicast with coopera...Show More

Optimal joint source-relay multi-resolution multicast networks

Zhi Chen;Pin-Han Ho;James She;Kshirasagar Naik;Payam Padidar

2016 IEEE Wireless Communications and Networking Conference
Year: 2016 | Conference Paper |
The paper studies the scenario of wireless multicast with a single transmitter and a relay that jointly deliver successively refined (or multi-resolution) sources to multiple receivers. By taking the end-to-end mean square error distortion (EED) as the performance metric, the problems of power allocation at the transmitter and relay are formulated. Due to nonlinearity of the formulations, a genera...Show More

Superposition transmission of layered encoded sources over non-orthogonal amplify-forward relay networks

Payam Padidar;Pin-Han Ho;James Ho

2014 IEEE Wireless Communications and Networking Conference (WCNC)
Year: 2014 | Conference Paper |
Cited by: Papers (1)
The paper investigates the broadcast of n-layered source codes over a single-relay network using a half-duplex nonorthogonal amplify-forward (HD-NAF) relaying protocol. Taking the distortion exponent, (i.e., the SNR exponent of the average end-to-end distortion) as the performance metric, we consider system operation in the high SNR regime. We first prove that the HD-NAF relay network with an n-la...Show More

In this paper, we consider broadcasting layered source codes over a single-relay network using a half duplex non-orthogonal amplify-forward (HD-NAF) relaying protocol. Distortion exponent (i.e., the SNR exponent of the average distortion) is taken to evaluate the system performance in the high SNR regime. We prove that the HD-NAF relay network with two-layered codes corresponds to a successive ref...Show More

Codebook-Based Precoding and Power Allocation for Nonregenerative Dual Hop Relay Systems

Payam Padidar;Fabien Heliot;Reza Hoshyar

2011 IEEE 73rd Vehicular Technology Conference (VTC Spring)
Year: 2011 | Conference Paper |
Cited by: Patents (3)
In this paper, we consider the precoding problem in the nonregenerative dual hop multi-input multi-output (MIMO) relay system. We propose a joint beamforming and power allocation method for a limited feedback system where a codebook-based beamformer is considered for each hop. The destination node selects the optimal beamforming codeword by relying on full channel knowledge of both source-relay an...Show More
