We consider a half-duplex wireless relay network with hybrid-automatic retransmission request (HARQ) and Rayleigh fading channels. In this paper, we analyze the outage probability of the multirelay delay-limited HARQ system with opportunistic relaying scheme in decode-and-forward mode, in which the best relay is selected to transmit the source’s regenerated signal. A simple and distributed rela...

A multiuser multiple-input multiple-output (MIMO) downlink communication system is analyzed in a Rayleigh fading environment. The approximate closed-form expressions for the probability density function (PDF) of the signal-to-leakage ratio (SLR), its average, and the outage probability have been derived in terms of the transmit beamformer weight vector. With the help of some conservative deriva...

In this chapter, the authors present the performance of multi-antenna selective combining decode-andforward (SC-DF) relay networks over independent and identically distributed (i.i.d) Nakagami-m fading channels. The outage probability, moment generation function, symbol error probability and average channel capacity are derived in closed-form using the Signal-to-Noise-Ratio (SNR) statistical ch...

Although LTE-Advanced system is targeted at enhancing the users’ throughput and increasing connection reliability, however user’s mobility tends to degrade the efficiency of the services and applications in terms of throughput degradation and outage probability reduction. Particularly this is during the handover from the source to the target eNBs. Therefore, the Carrier Aggregation (CA) techniq...

Analysis of Coded OFDM System over Frequency-Selective Fading Channels. (August 2003) Jun Zheng, B.S., Tsinghua University, P.R. China Chair of Advisory Committee: Dr. Scott L. Miller This thesis considers the analysis of system performance and resource allocation for a coded OFDM system over frequency selective fading channels. Due to the inseparable role taken by channel coding in a coded OFD...

The compute-and-forward (CMF) method has shown a great promise as an innovative approach to exploit interference toward achieving higher network throughput. The CMF was primarily introduced by means of information theory tools. While there have been some recent works discussing different aspects of efficient and practical implementation of CMF, there are still some issues that are not covered. ...

This paper investigates the outage probability and the throughput of relay networks with wireless information and energy transfer where the relays harvest energy from the transmitted radio-frequency signal of the source. Considering different power consumption models, we derive the outage probability for both adaptive and non-adaptive power allocations at the relay. With a total energy consumpt...
