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 before this SDR can be realised, is the design of an RF front end that can convert any digital signal to an analogue signal at any carrier frequency and vice versa. Quadrature mixing (QM) can be used to implement and analogue front end, that performs up and down conversion between the complex baseband centred around 0 Hz and the carrier frequency. By separating the tasks of frequency conversion and digital-to-analogue conversion, the latter can be performed at a much lower sample rate, greatly reducing the demands on the hardware. Furthermore, as QM can handle variable carrier frequency and signal bandwidth, this can be done without sacrificing reconfigurability. Using QM as an analogue front end may therefore be the solution to implementing SDR handsets. 2006-11-15T09:16:57Z 2010-06-01T08:46:19Z 2006-11-15T09:16:57Z 2010-06-01T08:46:19Z 2005-12 Thesis http://hdl.handle.net/10019.1/2334 University of Stellenbosch 1551973 bytes application/pdf application/pdf Stellenbosch : University of Stellenbosch |
