Fig. 1. Inter-chip wireless communication within computer chassis Impulse radio systems have received much attention as a possible architecture for UWB transceivers due to the large data bandwidth, low spectral interference with nearby channels, and simplicity of UWB transmitter/receiver architectures using mostly digital implementations. Due to the low emitted power spectral density of -41.3dB...

This paper presents an investigation of a radio receiver architecture to enable multi-standard (GPRS, WCDMA, HiperLAN2) implementation in mobile terminals. The architecture uses partial radio band digitisation at an intermediate frequency. Following circuit progress and industry trends (e.g. Moore’s law) we estimate components for the proposed architecture with acceptable power consumption to b...

This paper describes the implementation of an AM/FM radio receiver in Field Programmable Gate Array (FPGA). Using FPGA as the hardware platform, this approach brings together the flexibility of software and the speed of hardware to build a reconfigurable system, i.e. the behavior of the radio receiver can be changed by simply modifying the software without new hardware. RF modulated signals are...

A description is given of a radio controlled box for the remote release of insects. It consists of a plaster-lined plastic container fitted with a battery and radio receiver which control a servo to open and close the lid. Instructions for construction and use are given.

A 0.18μm single chip GPS receiver with 19.5 mA power consumption is implemented in 6.5 mm. A serial input digital control with additional testing structure not adding more than 4% to the Si area are used to the actual RF circuits in case of problems minimizing the number of Si runs. Index Terms — Testability, Test Structure, CMOS Radio, Global Positioning System (GPS), Receiver.

Time-hopping combined with pulse position modulation has been the original proposal for ultra-wideband systems. Spread spectrum techniques for multiple access and interference suppression are being considered for ultra-wideband radio systems. A digital impulse radio receiver using direct-sequence spreading is proposed in the paper and the signal processing scheme is investigated. Performance me...

Radio occultation measurements using the Global Positioning System (GPS) and a receiver in low-Earth orbit (LEO) have recently been shown to provide accurate profiles of atmospheric refractivity, pressure, water vapor and temperature with high vertical resolution [e.g. Kursinski et al., 1996]. When a GPS transmitter and receiver pair are on opposite sides of the atmosphere, the radio signal pro...

Wireless technology has given us a convenient way to transfer information from one point to other anywhere in the world. The last two decades have been the most dynamic in the history of wireless communication. The recent popularity of wireless networks results in many additional requirements of the system, especially the need of high data rates, demand for high quality multimedia services and ...

Channel properties influence the development of wireless communication systems. Unlike wired channels that are stationary and predictable, radio channels are extremely random and don’t offer easy analysis. A Radio Propagation Model (RPM), also known as the Radio Wave Propagation Model (RWPM), is an empirical mathematical formulation for the characterization of radio wave propagation as a functi...
