Automatic compensation for inaccuracies in quadrature mixers
(Stellenbosch : University of Stellenbosch, 2005-12)
In an ideal software defined radio (SDR), all parameters are defined in software, which
means the radio can be reconfigured to handle any communications standard. A major
technical challenge that needs to be overcome ...
Benefits to processor load for quadrature baseband versus radio frequency demodulation algorithms
(Stellenbosch : Stellenbosch University, 2008-12)
The continued advancement and improvement of software-defined radio technology has
been a key factor in furthering research into the implementation of most signal
processing algorithms at baseband. Traditionally, these ...
A software-defined radio implementation of maritime AIS
(Stellenbosch : University of Stellenbosch, 2007-12)
SumbandilaSat is the second South African satellite, and is scheduled to be launched in
April/May 2007. A software defined radio (SDR) automatic identification system (AIS)
receiver is proposed as a possible experimental ...
Implementation of an SDH simulator using SDR
(Stellenbosch : University of Stellenbosch, 2006-03)
A Synchronous Digital Hierarchy (SDH) point-to-point bi-directional link was implemented at a base Synchronous
Transfer Mode level 1 (STM 1) signal rate. The full STM-1 multiplexer was implemented and the functional ...
A Cross Platform Framework for Software Defined Radio
(Stellenbosch : University of Stellenbosch, 2007-12)
Software defined radios (SDRs) implement in software those parts of a radio which have
traditionally been implemented in analogue hardware. We explain the importance of this
definition and introduce reconfigurability and ...
Software modem for a software defined radio system
(Stellenbosch : University of Stellenbosch, 2007-03)
The use of older and slower protocols has become increasingly difficult to justify due to
the rapid pace at which telecommunications are advancing. To keep up to date with the
latest technologies, the communications ...
DAB implementation in SDR
(Stellenbosch : University of Stellenbosch, 2005-12)
The aim of this thesis is to implement a Digital Audio Broadcasting (DAB) system in a Software
Defined Radio (SDR). The physical modulation part of the DAB transmitter for one of the
transmission modes as well as its ...
Reusable software defined radio platform for micro-satellites
(Stellenbosch : Stellenbosch University, 2008-03)
This thesis describes the design and implementation of a software platform for software
defined radio (SDR). This platform was to form part of an experimental satellite payload.
Several other experiments were also housed ...
