Delay-Optimal Probabilistic Scheduling with Arbitrary Arrival and Adaptive Transmission
Xiang Chen, Wei Chen, Joohyun Lee +1
In this paper, we aim to obtain the optimal delay-power tradeoff and the corresponding optimal scheduling policy for an arbitrary i.i.d. arrival process and adaptive transmissions.…
Delay-Optimal Buffer-Aware Scheduling with Adaptive Transmission
Xiang Chen, Wei Chen, Joohyun Lee +1
In this work, we aim to obtain the optimal tradeoff between the average delay and the average power consumption in a communication system. In our system, the arrivals occur at each…
Delay-Optimal Buffer-Aware Probabilistic Scheduling with Adaptive Transmission
Xiang Chen, Wei Chen
Cross-layer scheduling is a promising way to improve Quality of Service (QoS) given a power constraint. In this paper, we investigate the system with random data arrival and adapti…
Power Allocation and Time-Domain Artificial Noise Design for Wiretap OFDM with Discrete Inputs
Haohao Qin, Yin Sun, Tsung-Hui Chang +4
Optimal power allocation for orthogonal frequency division multiplexing (OFDM) wiretap channels with Gaussian channel inputs has already been studied in some previous works from an…
Optimal Power Allocation for Two-Way Decode-and-Forward OFDM Relay Networks
Fei He, Yin Sun, Xiang Chen +2
This paper presents a novel two-way decode-and-forward (DF) relay strategy for Orthogonal Frequency Division Multiplexing (OFDM) relay networks. This DF relay strategy employs mult…
Optimal Power Allocation for OFDM-Based Wire-Tap Channels with Arbitrarily Distributed Inputs
Haohao Qin, Yin Sun, Xiang Chen +2
In this paper, we investigate power allocation that maximizes the secrecy rate of orthogonal frequency division multiplexing (OFDM) systems under arbitrarily distributed inputs. Co…
