Data Packets
Received Packets
PC
IP-Network
PC

• Sample speech signal
• Extract and quantize model parameters
• Put encoded speech in packets
• Send over IP-network (8kbit/s)
• Simulate package loss, delay and bit error
• Synthesize speech from received data
• How should lost packets and clock drift be
  handled?

13
Project 3 Can2can

• Acoustic Communication using a single Wire
• Duplex communication on the same wire
• Emphasize on high data rates (9,6Kbit/s _at_ Pbe
  0.1)
• Adaptive to different wire lengths and types

14
Project 4 OFDM Modem

• Datacommunication over a telephone wire using
  multicarrier modulation (as in e.g. xDSL, WLAN).
• Duplex communication using FDD high-speed
  downlink, low-speed feedback uplink
• Adaptive modulation on the different downlink
  sub-carriers
• Interleaving and channel coding

15
Project 5 Loudspeaker linearization

• Use pre-distortion to make a loudspeaker and an
  amplifier sound better
• Combine with room-cancellation?
• How good can you make it sound?

16
Project 6 Smart pinball.

• a pinball game
• a web-camera
• a PC with DSP
• real time acquisition processing of pictures.

• detect the ball on the video
• operate flippers when required
• have a drink while the pinball is playing -)

17
Project 7 MIMO with MUMS

• MIMO System over real radio.
• 2 PC. 2 DSP. 2 RX. 2TX.
• MUMS software package available.
• Compare
• W-OSTBC
• Spatial multiplexing.
• Differential STC.
• All with rate-adaption up to 35kbit/s.
• H known in TX using feedback channel.

18
Project 8 MIMO without MUMS

• MIMO System over real radio.
• 2 PC. 2 DSP. 2 RX. 2TX.
• Programming from scratch (no MUMS).
• Differential space-time coding.
• With/without knowledge of H in RX. No H knowledge
  in TX.
• BMP_at_15kbit/s

19
Project 9 Acoustic MIMO

• Two loudspeakers representing antenna array at
  transmitter
• Two microphones as antenna array at the receiver
• MIMO communication with adaptive modulation for
  maximum performance
• Illustrative user interface with clickable block
  scheme of system
• Signals and parameters displayed in real-time!
• In many ways more challenging than MIMO over
  radio.
