Learning outcomes
After completing the course, a student has good understanding of the key RF-functionalities and related performance issues when designing the analog and digital signal processing blocks for communications receivers and transmitters. She/he can also explain the possibilities and challenges of increased use of digital signal processing algorithms for implementing or enhancing the RF functionalities.
