| Description:
| Aims & Learning Objectives: To introduce students to more advanced topics in digital communication systems. On completion of the course, the student should be able to understand the main operating features of digital communication systems, including the relative performance of the various modulation methods, the efficiency of error detection and correction methods and the security of encryption systems. Content: Digital modulation techniques: review of binary modulation and demodulation; QPSK, OQPSK, MSK; QAM and trellis coded modulation. Channel coding: linear block codes for error detection and correction; cyclic codes and shift register generation and detection; Hamming, BCH, RS and Golay codes. Convolution coding: definition, generation and distance properties of convolution codes; Viterbi decoding with hard and soft decisions; sequential and feedback decoding; interleaving. Spread spectrum techniques: overview and pseudonoise sequences; direct sequence and frequency hopping systems; synchronisation. Encryption and decryption: cipher systems and secrecy; practical security; stream encryption; public key cryptosystems. |
