LB communication systems can be considered as a potential candidate for ultra LPWAN because of their low cost and power consumption. In this paper, we comprehensively analyze modulation from various aspects, i.e., temporal, spectral, error performance characteristics. First, propose signal model signals that accounts the limited number loads in tag. Then, investigate spectral properties signals...

Direction finding has been extensively studied over the past decades and a number of algorithms have developed. In direction finding, theoretic performance prediction is fundamental problem. This paper addresses analysis issue interferometer-based 2D angle arrival estimation using uniform circular array (UCA). We propose an analytic method for interferometer in presence Gaussian or error phase ...

We propose an analytical method for evaluating the TCP throughput performance in a wireless cellular network environment, where the slotted ALOHA protocol is adopted as a data link layer. By using our method, we show that improving throughput at the data link layer level does not necessarily lead to the TCP throughput improvement. Furthermore, we evaluate TCP throughput by considering transmiss...

Molecular communication and the Internet of Nanothings (IoNT) are emerging research hotspots recently, which show great potential in biomedical applications inside human body. However, how to transmit information from body IoNTs outside devices is seldomly studied. It well known that nervous system responsible for perceiving external environment controlling feedback signals. exactly works like ...

It is known that one of the essential building blocks of turbo codes is the interleaver and its design using random, semi-random (S-Random) and deterministic permutations. In this paper, two new types of turbo code interleavers, Modified Block S-Random (MBSR) interleaver and Modified Matched S-Random (MMSR) interleaver are proposed. The design algorithm for the new interleavers is described in ...
