Software Defined Radio as a DS-CDMA Receiver
Programmable radio is one of the latest trends in the construction of multi-standard receivers. The technology, called Software Defined Radio (SDR), is also an ideal test platform that allows trying out different algorithms of signal receiving. This particular feature led to choose this platform to implement a DSCDMA receiver (Direct Sequence Code Division Multiple Access). This receiver is a part of the radio-location system called AEGIR. The main task of the receiver is to calculate geographical position on basis of received signals from ground stations. That is why Software Radio has been chosen. It allows a gradual upgrade of data processing algorithms.
