In this paper, we propose a simple header detection technique to identify multiple device connections for finite length wireless Internet-of-things (IoT) networks. The Hadamard codes are selected to guarantee low computational complexity, while finite length, defined as finite number of time-slots, is considered to fulfill the requirement of low network latency required by the fifth generation (5G)...
Efficient channel coding techniques for wireless communications become important solutions to meet the 5G requirements, especially on the aspect of high reliability and low latency communications in the Internet of Things (IoT) era. This paper proposes new degree distributions of Raptor Codes for devices supporting IoT communications with Low Density Generator Matrix (LDGM) codes as the precode, called...
In this paper, we propose new Raptor codes suitable for uplink Internet of Things using single carrier transmission technique (SC-IoT) with low density parity check (LDPC) codes as the precode, called LDPC-Raptor codes. The utilization of LDPC as the precode is to guarantee high capability of error correction for better Raptor codes performance while keeping the computational complexity low. Raptor...
This paper proposes a detection technique based on factor graph (FG) to estimate the position of radio wave emitter. To obtain accurate estimation, we combine received signal strength (RSS) and direction of arrival (DOA) schemes into a single factor graph, called joint RSS-DOA, where soft information as mean and variance of the estimated target position are exchanged between the two schemes. The performance...
This paper presents finite-length performance analysis for wireless super-dense networks comprising two multiway relays (SDN-2MWR) to support full data-exchange among massive number of users/devices over Rayleigh fading channels. In practice, finite-length analysis is important since the networks should serve users/devices with low latency indicated by short number of time-slots. Due to the nature...
Highly dense wireless networks is one of the most important solutions for spectrum shortage expected by 2020. Motivated by a generally assumption that direct links between users in HD-MWR networks are usually ignored, this paper proposes high-dense multiway relay (HD-MWR) networks exploiting available direct links as side information (SI) to serve even higher number of users or devices required for...
In this paper, we consider the problem of transmitting two correlated binary sources over orthogonal multiple access relay channel (MARC), where two sources are communicating with a common destination with the assistance of a single relay. We assume decode-and-forward relaying strategy, and bit-wise exclusive or (XOR) network coding is performed at the relay node. First, a joint source-channel-network...
