Automated control signal reception acknowledgement system using nRF24L01P wireless transceiver module and Arduino

Automated control signal reception acknowledgement system using nRF24L01P wireless transceiver module and Arduino

This is a system developed based on nRF24L01 and Arduino. The nRF24L01 is used as wireless transceiver module which is a low cost and easier to implement wireless module. Arduino is used as the Microcontroller Unit (MCU) [1, 2]. Here any of the Arduinos can be used such as Uno, Mega, and Nano. But one problem is that the Nano is a low power MCU which outs a low output current and that is if somebody use nRF24L01+PA+LNA module than it will not operate [3]. nRF24L01 module goes with Nano perfectly. This is the only precaution with Arduino Nano and nRF24L01 module. In this system the transmitter will transmit a control signal or monitoring signal. Then the receiver will make a reply that is an acknowledgement message will be sent automatically to the transmitter from the receiver unit immediately after receiving the control signal. If the acknowledgement message is not received in transmitter end that means the receiver is not receiving the control signal and that ’ s why it is not responding with a reply or acknowledgement. Through this system a controller

Tile Type Multi Channel Transceiver Module Applied for Phased Array Antenna

Tile Type Multi Channel Transceiver Module Applied for Phased Array Antenna

Active phased array transceiver module is the key component of phase array an- tenna. The overall volume and weight of phase control antenna array depends on the individual T/R modules [1]. Therefore, from the beginning of 1980s, many countries engaged in research on how to reduce the volume and weight of a single T /R module with a large capital investment and scientific research strength [2]. Current research focuses on tile type structure of T/R module. Be- cause the volume of T/R module of tile type structure is only 1 /4 the size of the traditional brick structure [3]. So it has incomparable advantages of reduced vo- lume and weight, and it is easy to implement large-scale array [4].

Design and Implementation of Mesh based Multimedia Transmission System at 400MHz

Design and Implementation of Mesh based Multimedia Transmission System at 400MHz

The central Mesh node, the schematic diagram is shown in Fig. 3. Because the meshing mode of the Mesh network is adopted, in theory, the status of each node in the network is equal, and any node can be used as a central Mesh node or a common node, but considering the actual situation, only one of the nodes is selected as the center Mesh node. The difference between the central Mesh node and the common Mesh node structure is mainly increased, and devices such as a display and a hard disk recorder are added. The central Mesh node receives the multimedia data transmitted by other Mesh nodes through the signal transceiver module, and the data is transmitted to the hard disk recorder and stored in the hard disk, and the received picture is displayed on the display, and if it is voice data, it is transmitted from the earphone.

Design of a Li Fi Transceiver

Design of a Li Fi Transceiver

The latest uproar in this era is about a technology termed as Light Fidelity or more commonly known as Li-Fi. There are currently two trends being seen: First, the extension or enrichment of wireless services and other being in- creased in user demand for these services, but the available RF spectrum for usage is very limited. So the new technology of Li-Fi came into picture, which uses visible light as a source of communication. Li-Fi is the most recent de- velopment which is resourceful. In this technology, LEDs are used to transmit data in the visible light spectrum. This technology can be compared with that of Wi-Fi and offers advantages like increased accessible spectrum, efficiency, security, low latency and much higher speed. This research paper aims at de- signing a Li-Fi transceiver using Arduino that is able to transmit digital data. The hardware has been designed using Eagle CAD (version 7.1.0) tool and Proteus design tool (version 8). The software coding is done by using Java (version 8). Successful transmission and reception of text, image and video signals is carried out on the transceiver. Hence this research work gives an innovative way of designing a transceiver which works by using off the shelf low cost components and using visible light spectrum.

Robust transceiver design for reciprocal M × N interference channel based on statistical linearization approximation

Robust transceiver design for reciprocal M × N interference channel based on statistical linearization approximation

This paper focused on sum rate improvement of the Max-SINR algorithm under CSI error. In the first proposed scheme, each transceiver adjusts its filter by maximizing the expected value of the signal-to- interference-plus-noise ratio (SINR). Realized SINRs for different realizations of the CSI error matrices, are sam- ples of the SINR random variable. In some cases, this random variable may have large variance. Therefore, the realized SINRs could be very far from the expected value. In the second proposed algorithm, each node ad- justs its transmit/receive filter to minimize the variance. This design hedges against variability.
