  Różnorodność standardów systemów radiokomunikacyjnych, w tym telefonii komórkowej i bezprzewodowej, przy dużej ruchliwości ich abonentów, powoduje, że niezbędne jest skonstruowanie wielosystemowego terminala ruchomego, mającego techniczne możliwości współpracy z systemami radiokomunikacyjnymi działającymi w różnych standardach. W ten sposób zrodziła się idea radia definiowanego programowego SDR (Software Define Radio), bazująca...

  - SENSORS - Year 2021

  In the radiocommunication area, we may observe a rapid growth of new technology, such as 5G. Moreover, all the newly introduced radio interfaces, e.g., narrowband Internet of Things (NB-IoT), are strongly dependent on the software. Hence, the radiocommunication software development and optimization, as well as the 3GPP technical specification, should be introduced at the academic level of education. In this paper, a software-defined...

  - Year 2010

  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 to try 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). The use of SDR allows for a gradual upgrade of data processing...
