  1. Welcome toEQ2440 Project in Wireless Communication EQ2435 Wireless Communication-Business EQ2430 Project Course in Signal Processing and Digital Communication Kick-off Meeting February14, 2014 Per Zetterberg School of Electrical Engineering

  2. Program • Who are we? • Introduction to the course. • Presentation of the projects. • Application form. https://www.kth.se/social/course/EQ2440/

  3. Who are we? Per Zetterberg Course responsible Sebastian Schiessl TA, PhD Student ArunVenkitaraman, TA, PhD Student EshanOlfat TA, PhD Student Martin Ohlsson, AndroidGuru NimaMoghadam, PhD student SenayNegusse, Phd student

  4. Course Facts • Credits: 12. • Grade: ECTS. A-F. • Group work. • Number of students per group 3-7 (mostly 4-6). • You choose among a set of “eligible” projects. • Youtellusaboutyourskills. • We form groups and assign a leader. • One Project assistant per group. • Course responsible: Per Zetterberg. • Prototype responsible: You! • Goals and time-table are specified, how to achieve this is up to the team.

  5. Real-time based projects • Real-time processing on smart-phone or Ubuntu PC. • Receiving data from sensors (e.g. A/D converters) transmitting data on actuators (e.g. D/A converters). • Presentation on of results on screen. • The signal processing in real-time is one of the major challenges due to the resulting code/algorithm structure and computational-time constaints. Group member roles: • Programmer . • Matlab/theory developer. • Group leader/generalist.

  6. Areas groups will work with • Algorithms (Matlab). • Project management. • Reports (Word or LaTeX) • Coding (Eclipse or emacs) • Web-pages. • Oral presentation (PowerPoint) • Setting up experiments, connecting cables. • Integrating. • Debugging, debugging, debugging. • Project management: projectleader. • Smartphone-programming (android, eclipse) • PC-programming (gcc-realtime) • Experiments. Some will work with

  7. Smartphone/android based projects Features used in our projects: • Display : plots and text. • Camera • Microphone. • Loudspeaker. • Magnetometer • Wifi RSSI measurements. • Send data using Wifi. • Acceloremeters. • Gyros. • Touch screen.

  8. USRP based projects • USRP = Universal Software Radio Peripheral • Used to transmit and receive wideband (4-8MHz) signals over real radio transmitters and receivers. • Matlab interface to download and upload I&Q samples for off-line development. • Real-time implementations are the goal. • The signals are distorted by real-world RF-impairments (non-linearities, intersymbol-interference, phase-noise, frequency offset).

  9. What would be your advice to a student who chooses this course next year ? • Don’t choose another course at the same period. Start really early with everything. • Start working from the beginning • Work hard in the beginning and try to ease up in the end • Work hard in the beginning of the project • Start working from the first day, and don’t take more than a week off, during the Easter • Choose it, but take it alone, with nothing else. • Work work work. • Take the course if you like to work hard. • Start early. Implement on DSP asap. • Don’t read other courses in parallel • Take it!

  10. Eligible Projects • In-flight file-transfer using 3mm-cable • Teleconference with noise cancellation • Smart-phone multi-channel sound • Wireless transmission at 60GHz

  11. Project #1:In-flight file-transfer using 3mm-cable • File-transfer on airline -no radio allowed! • Use loudspeaker and microphone • Use a 3-mm cablebetween the phones. • Push the data rate to the limit. • Challenging modulation and coding problem!

  12. Project #2: Teleconference with noise (interference) cancellation Internett Noise Conference room Talk Talk Interference cancellation! Adaptive signal processing!

  13. Project #3:Smart-phone multi-channel sound And IIII willalways love youuu ….. Bittersweet memories

  14. Project #3:Smart-phone multi-channel sound And IIII willalways love youuu ….. TA And IIII willalways love youuu ….. • Estimate delays • Timing advance (TA) orders over internet TA

  15. Project #4:Wireless Transmission over 60GHz • 60GHz = mm wave. Highfrequencies => high data rates. 5G research. • Synchronization • Modulation/demodulation • Coding • Phasenoise 60GHz USRP USRP 60GHz

  16. Project Application Form • Deadline February 20th. • Name, project choice, skills. • Group formation by March 17. • Project manager assigned (group can request change). • More information on projects on course homepage: • Sign the participant list and fill in your email. • See you March 24 at 10.15 in B24! https://www.kth.se/social/course/EQ2440/
