New information for the Spring Semester, 2017:

The two basic trends of our time are as follows:
  • everything goes wireless, and
  • .
  • everything becomes software defined.
Software Defined Electronics (SDE) is a brand new approach introduced recently. In SDE, the telecommunication systems and measurement equipment are implemented in baseband (BB) and entirely in software. The transformation of data sequences generated in BB into the analog RF/microwave signals is performed by a universal hardware (HW) device. Because SDE implements all signal processing tasks in SW, the SDE approach offers an extremely high level of flexibility which is required in many advanced applications such as in Cognitive Radio (CR), Software Defined Radio (SDR) and Virtual Instrumentation (VI).

Addition to the theory and practice of advanced mobile telecommunication systems, EIE579 also discusses software defined electronics. To equip the students with a solid theoretical and practical skill, laboratory experiments are included where a 915-MHz FSK radio link and different BPSK transceivers are implemented and tested. In the radio link built in the laboratory experiment one networking device is implemented by a conventional HW-type SoC FSK transceiver (Texas, TRF6900EVM), while the other device is implemented by the SDE approach. The transformation between the BB data sequences and the analog microwave signals are performed by a Universal Software Radio Peripheral (USRP).

For further information on the SDE approach please refer to the following tutorial:
Picture of testing a 915-MHz FSK radio link in EIE Communications Laboratory (DE502). The green Printed Circuit Board (PCB) on the left side is the TRF6900 Evaluation Module, while the grey box on the right side is the USRP device.

Picture of testing a QPSK transmitter built with a raised cosine pulse shaping filter in EIE Communications Laboratory (DE502). The SDE concept was used to implement the QPSK transmitter entirely in SW and the USRP device (notice the gray box) was used to reconstruct the analog microwave signal from the BB data sequence.
