A Software Defined Radio Receiver Test-bed

چکیده
This paper identifies the issues that are important in the design of a SDR receiver. Receiver architectures are first discussed, and the conclusion drawn that the conventional superheterodyne structure is most appropriate for a SDR receiver. Issues associated with image rejection, and receiver linearity are discussed. The design of a sweepable preselect filter is discussed in detail. Design considerations for a practical SDR test-bed are presented.

An Analogue Front-end Test-bed for Software Defined Radio
A Software Defined Radio (SDR) is a radio receiver and/or transmitter, whose characteristics can to a large extent be defined by software. Thus, an SDR can receive and/or transmit a wide variety of signals, supporting many different standards. In our research, we currently focus on a demonstrator that is able to receive both Bluetooth and HiperLAN/2. This helps us to identify problems associate...

Accurate positioning is an essential element of next generation Software Defined Radio (SDR) applications such as cognitive radios, telematics, and E-9-1-1, leading to an increased demand for GPS waveforms on SDR platforms. The Software GPS Receiver (SGR) developed in-house at NAVSYS implements functionality largely in software, and uses a reprogrammable hardware platform that can also be confi...
متن کاملA Software Defined Radio Test-bed for WLAN Front Ends
In our Software Defined Radio (SDR) project we aim at combining two different types of standards, Bluetooth and HiperLAN/2 on one common flexible hardware platform. The HiperLAN/2 hardware is that complex compared to the Bluetooth hardware, that Bluetooth capability may be added to the HiperLAN/2 platform at limited cost. The question is how to do this. In this paper we first describe the radio...
