Lecture Topics:

1. Introduction; Review of probability and random processes. (Ch. 1, Ch. 2 in textbook)

2. Optimal receivers and performance calculations for communication over AWGN channels: signal spaces; MAP receivers; performances of different modulation formats; link budget analysis. (Ch. 5, Sec. 4-2)

3. Carrier and symbol synchronization. (Ch. 6)

4. Signaling for bandwidth-limited channels: signal design for zero ISI and controlled ISI; optimal receiver in the presence of ISI. (Ch. 9)

5. Error-control coding: linear block codes: hard-decision (syndrome) and soft-decision decoding; convolutional codes: Viterbi algorithm. (Ch. 8)

6. Application examples.
