Abstract:
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 DS-CDMA receiver (Direct Sequence Code Division Multiple Access). This receiver is a part of the radiolocation 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. The main goal was to create a wireless receiver that allows calculating the correct position on the basis of the received signals and the processing time will be minimized as much as possible. This paper mainly focuses on algorithms in terms of correctness of the received signal and, what is equally important, its processing time.
