1 Software Defined Radio and receiver (Softrock) demo G0CHO 10 th June 2008
2 What is Software Defined Radio? My SupaDupa DX5000 has lots of DSP, isn t that SDR? American National Standard, Telecom Glossary An SDR consists of a receiver and/or transmitter with the following properties: (a) the received signal is digitized and then processed using software-programmable digital signal processing techniques (digitization may occur at the RF, IF, or baseband); and (b) the modulated signal to be transmitted is generated as a digital signal using software-programmable digital signal processing techniques. The digital signal is then converted to an analog signal for transmission (the conversion to analog may occur at baseband, IF, or RF).
3 What is Software Defined Radio? There are two main features that seem to define amateur radio SDR ; As defined previously software is used for modulation/demodulation. The software can be field upgraded by the user.
4 Why Software Defined Radiogeneral? Flexible New modes New features Less RF hardware Lower cost (up to 70%) Increased reliability Improved performance Use ideal component values Reduced Obsolescence
5 Why Software Defined Radio- for amateur radio (1/2)? Totally configurable Potentially tweak every aspect of performance Numerous options / functions When open source software used Potentially huge pool of programmers Download free updates & extras Experiment with software Assist with evaluations
6 Why Software Defined Radio- for amateur radio (2/2)? New possibilities for experimentation Network radios Simultaneous voice, data, and video D-Star is an exception
7 Magic! SDR how does it work? The magic of mathematics! Any signal can be described mathematically, e.g SSB = Convert an analogue signal into a digital representation (A to D converter) Generate an analogue signal from a digital representation (D to A converter)
8 SDR how does it work? Digital generation of a sine wave Sampling rate/frequency
9 SDR how does it work? Sine wave conversion to digital Sampling rate/frequency must be twice the highest wanted refeqency - Nyquist
10 SDR how does it work? A/D conversion Flash comparator for each O/P value (e.g. 255 for 8 bit) Successive approximation
11 SDR how does it work? A/D conversion Delta-Sigma Used in soundcards
12 SDR how does it work? D/A conversion R 2R ladder Weighted summing amp
13 SDR why now? (1/2) SDR has been around for some years but hasn t taken off until relatively recently Dedicated hardware was required, A/D & D/A converters plus microprocessor Build it yourself or buy evaluation kit Limited scope to exchange software
14 SDR why now? (2/2) The relentless march of computing power & the web has made SDR more accessible Modern PC quite capable of processing Soundcards have two channel A/D & D/A converters But beware many laptops only have mono microphone inputs USB soundcards Easy access to other interested amateurs and software
