We propose a new analytical approach to evaluate the average packet error rate (PER) of a
conventional packet transmission system over a quasi static fading channel, by presenting …

Problems formulated in terms of logarithmic or exponential equations often use the Lambert
W function in their solutions. Expansions, approximations and bounds on W have been …

The optimum energy efficient and spectral efficient designs for type-I automatic-repeat-
request (ARQ) systems in Rayleigh flat fading channels are studied in this paper. Three …

The hybrid relay selection (HRS) scheme, which adaptively chooses amplify-and-forward
(AF) and decode-and-forward (DF) protocols based on the decoding results at the relay, is …

Opportunistic relaying has the potential to achieve full diversity gain, while random linear
network coding (RLNC) can reduce latency and energy consumption. In recent years, there …

This paper discusses the energy-and spectral-efficient transmissions for delay-constrained
wireless communication systems utilizing hybrid automatic repeat request (HARQ). Three …

The combination of non-orthogonal multiple access (NOMA) and transmit antenna selection
(TAS) techniques has recently attracted significant attention due to the low cost, low …

An energy-efficient orthogonal multiple-access relay channel (MARC) system is developed,
where accumulator and differential detection (DD) are used at the source and relay nodes …

In this paper, we design an integrated protocol that jointly optimizes the performance of the
physical, medium access control (MAC), and network layers. Our goal is to minimize total …

Unlike the previous work, which relies on cyclic redundancy check (CRC) to decide the
decoding accuracy at the relay nodes, in this paper, we propose a simple threshold-based …
