CRC (cyclic redundancy check) block was developed on FPGA (field programmable gate array) in order to meet the needs for simple, low-power and low-cost wireless communication such as Zigbee. Zigbee operates primarily in the 2.4 GHz band, which makes the technology easily applicable and worldwide available. This paper gives a short overview of CRC block in the digital transmitter based on Zigbee standard...
Digital transmitter was developed on FPGA (Field Programmable Gate Array) in order to meet the needs for simple, low-power and low-cost wireless communication such as Zigbee. Zigbee operates primarily in the 2.4 GHz band, which makes the technology easily applicable and worldwide available. However, this paper only covers the bit-to-symbol block and the symbol-to-chip block of the digital transmitter...
Wireless system is one of the technologies currently applied in agriculture to improve quality, save labour costs, increase yields, and conserve water. A real-time wireless monitoring system for measuring climatic environment parameters of rain shelter house (RSH) for chili plantation was developed. The wireless monitoring system integrates the hardware and software components for the measurement...
To enhance the throughput of ad hoc networks, dual-hop relay-enabled transmission schemes have recently been proposed. Since in ad hoc networks throughput is normally related to their energy consumption, it is important to examine the impact of using relay-enabled transmissions on energy consumption. In this paper, we present an analytical energy consumption model for dual-hop relay-enabled medium...
Technological advances allow handheld devices to be equipped with faster processors and wireless interfaces, making the performance comparable to laptop Computers. In this paper, we describe real-time video streaming over heterogeneous networks namely Bluetooth, Wi-Fi and GPRS-EDGE. The wireless channel used for communication in different network varies in their Bandwidth, supported Bit rate and Unequal...
