Data TransmissionLaajuus (3 ECTS)

Objective

After completing this course the student understands the importance of error control for high quality digital transmission. He/she is able to choose the error control method for a certain application. He/she can also design some linear block codes and cyclic codes using combination logic and shift registers.

Content

Error control methods, error detection/retransmission (ARQ) and error correction (FEC)
Performance of error control methods and residual error rate
Error correcting codes: Block codes, cyclic block codes, convolutional codes, turbo codes.
Trellis Coded Modulation (TCM)

Qualifications

Communication Networks

Assessment criteria, satisfactory (1)

- Can encode data with the help of a given block code
- Can correct and detect transmission errors with the help of a given block code
- Can calculate the residual error rate of a repetition code and with the help of that understands how the quality of an error control code depends on the code rate
